i've had some sort of visual flashback before and i've only done weed, DXM, and mushrooms. my keyboard multiplied, with a low opacity duplicate image and quickly layered ontop of itself. it was pretty weird. it went away fairly quickly despite me wanting it to stay.

they are fun, just got to be smart about using them and there won't be any problems.

Judging from my personal experience... He won't die from it or anything.  I must say that I LOVE it though... I haven't done it in about 8 or 9 months, but it's a very good feeling if you're not afraid to put anything up your nose.  But I'm nothing like Tony Montana... lol.

Yeah, it IS a good feeling... for about 20 minutes, until you come down and feel worse off than you began, plus you're down whatever amount you paid for it, and most likely half of what went up your nose is baking soda or shit like that.

And yeah, you can die, especially in combination with other drugs that might amp you up, if your heart explodes.

@Norn: no, tobacco is not required, it is just prefered by most people as the weed will burn better in a joint this way, and will make the joint bigger. Although, it is actually better without the tobacco as tobacco will cause the high to die out faster.

I haven't been here in a while and spotted this and thought i would share some experiences.
Drug background:
-weed, A LOT
-LSD
-Ketamine
-DXM
-benedryl/gravol (i forget the chemical names :/)
-Shrooms
-Ecstacy/Pure MDMA
-Alcohol
-Oxycodone
-Salvia
-Nitrous Oxide
-Dexedrine
-Ritalin

Weed:
Fun drug, i get really lazy and stupid but can have deeper thoughts if aimed for and decreases boredom for me. Plus helps me sleep/calm down on stimulants as well as acting as an anti-nauseant. Plus its a community drug to me, so all my friends always smoke each other, which makes it less costly for me (i do pay too, im no mooch :/)

LSD:
Probably one of my favourite drugs, it fucks with all of your senses in a way that is extremely difficult to describe, makes you laugh at nothing and will cause you to have extremely strange and foreign thoughts on everything. It also causes open-eye visual distortions (colours flow out of boundaries, objects change colours, etc.) as well as closed-eye patternings. Your sense of time is also fucked with, time will speed up and slow down and you will never have any sense of what time it is. What people don't seem to understand though, is that although LSD is a hallucinogen, visual hallucinations are just distortions and psychedelic patternings, as LSD is a psychedelic, actual hallucinations (like say, seeing your best friend and talking to him although he is not there, is caused by deleriants (such as datura/bella donna/gravol/benedryl))

Ketamine:
Another type of hallucinogen, but neither psychedelic nor deleriant, ketamine is a disassociative, which basically disassociates the mental self from the physical self. Basically its like being drunk + tripping out. Very fun, although it is physically addictive and isnt a very long lasting drug. luckicly 15$ will get me a vial which will last about a night for me (if my tolerance is minimal, another thing i dont like about it is that your tolerance builds waaayy too fast. for me, my dosage will significantly increase throughout the night, like say one bump at the beginning will put me in a k-hole, while at the end of the night i require like 2-3 bumps to get a nice high off of it) also it has terrible drips. otherwise very fun for every once in a while. Plus side to k is that there is no hangover/bad comedown.

DXM:
Yes, robitussin. Yes, a lot of my friend make fun of me for it, saying it is very stupid (although they are the stupid ones, when i take it i am taking 1 single, safe drug. most of my friends take e which is made up of many different, unknown, unsafe drugs...it pisses me off sometimes actually, as DXM isn't somekind of pussy drug, nor is it stupid imo) Another disassociative (similar to k, only longer lasting) To me it is really fun, but i always get a bad case of robo-walk (stiff, awkward walking...kind of like a robot) and it makes me etremely dehydrated. but i like it much better than k and its cheaper. also to everyone who's drinking this shit, you do realize you can buy robitussin gel caps, which are pure dxm and really easy to take (and easier to monitor your dosage).

Benedryl/Gravol:
I fucking hate these drugs so much. I have done them several occasions, fucking myself up. The reason i did them was because they are deleriants similar to datura (which i wanted to try, but datura is harder to find and is impossible to find an exact dose). All these do is make me tired and it difficult for me to keep any thought (acute amnesia is caused, you'll have a thought in your head and you go to say it but as you are talking you will either forget what you are talking about or even forget that you were talking) Also, it is near impossible to tell the difference between real-life and hallucinations. the last time i ever did it was one day i decided to take 24 benedryls (each of 25mg i believe) and at first i actually liked it, as i got the full on effects and plus i met up with my friends who brought me to their place smoked me some pot and took care of me. of course this is where it went all wrong. next thing i know im wandering the streets with my friends heading to a local show, then im at a police station being questioned, apparently i was trying door handles in the parking lot. also, apparently i wasn't with anyone and it was actually 1 in the morning, which i found out after saying my mom was golfing and the cop said "golfing at 1 in the morning?". luckily no charges, but it was a very frightening experience and i have no idea what had happened. If you are going to try these, i do suggest having a sober sitter who will take care of you or lock yourself in a room with no dangers.

Shrooms:
Another psychedelic similar to LSD, although shorter lived and more "giggly" and time feels dilated (staring at a clock will make it seem like seconds take forever). My favourite hallucination would have to have been when i did 4 grams my first time and it seemed like the ground was forming waves like the ocean and i was trying to step over the waves while laughing really really hard. fun times.

Ecstacy/Pure MDMA:
First drug after weed that i tried and at first thought it was a great drug (and actually developed a mental dependance for it...bad idea) but now i only do it every once and a while as it actually is a very shitty drug and to me is only fun in huge doses with a low tolerance...yes i have mildly overdosed many a time. I like pure mdma a lot more than the pills, as mdma is a lot cleaner feeling, easier to sleep on and has a much easier to handle hangover. Makes you energetic, happy, loving, caring, makes it easier to connect to people and you talk a lot. Also make you clench your jaw like a bitch and a little harder to get an erection (although, it is even harder to cum if you can get a boner). Be very careful though, e will make you very carefree so you may say some things that you dont want people to know.

Alcohol:
Must i describe alcohol? oh well, despite the taste (and my pussyness to handling the taste) it is veryy fun to me...i love getting really dumb and rowdy and stumbling all over the place. unfortunately for me, although i do know my limit, i tend to ignore once drunk. and for me puking is just an excuse to drink more lol.

Oxycodone:
I actually really liked oxycodone, it slows you down a lot and numbs pretty much all pain as well as making you stumble over your words and laugh more. wasn't too long of a high, but it wasnt too too short. not something i'd do often though (as oxycodone is extremely addictive)

Salvia:
A really cool drug, it only truly worked for me once, but when it did i saw everything grow above me and trees spelt out unrecognizable words (the same way LSD and shrooms do for me, i can tell they are words but i cant seem to make out what they say) and then i was flying through the sky then everything went black and i woke up like 20 feet from where i smoked it. According to my friends (and a video on a phone) i fell to the floor and started laughing and asking what the fuck was wrong with me, and then i got up and started running away screaming, which then my friend tackled me and i woke up. Also, i learned something, for salvia to work properly (this explains why most of the time people don't get "high" off of it) it is best to be in a quiet environment, everyone must stay silent as recognizable/real sounds will pull you back into reality, canceling the effects of the salvinorin-a.

Nitrous Oxide:
pretty fun, numbs me up makes me laugh my ass of at nothing and trip out. Waayy to short though, last about 5-10 minutes for me. luckily i work in a grocery store and can easily steal whipped cream aerosol cans...so i get this for free

Dexedrine:
A prescription amphetamine for people with ADHD/ADD i took 3 before gym class one time, and lets just say i couldnt stop once, we had a 12 minute run and i kicked some ass (which was funny cuz im a smoker and everyone in my class was in shock, although people who knew me better figured i was on some type of drug) Makes you happy and talk alot, along with jaw clenching.

Ritalin:
Similar to dexedrine except nowhere near as potent, and only seem to do anything if you snort a few of them. fun enough plus i have friends who are prescribed this and i get it for free. Although one time i took 7 or so plus like 3 concerta's (none of these were snorted) and man was it fun. Although i still prefer psychedelics/disassociatives to stimulants anyday.

long enough post i guess. i finally found a connection for mescaline/dmt, so i should be getting these soon

man now my desire to try salvia has been increased tenfold

same i really, really want to try it.

Wow Synu that is probably not good for you.

yea, my body is probably all fucked up, but its all about moderation...so i don't really notice the negative effects too much

and about salvia just remember a sober sitter and a quiet, peaceful environment. its fun and legal, but its short duration makes it not something you'd do a lot, but its good for a nice mind expanding experience. its pretty cool

http://erowid.org/chemicals/ketamine/ketamine.shtml

i guess they are either lucky, or strong-willed. i've had cravings before and i know several people addicted to the stuff, its not the same kind of physical addiction as coke or heroin, but it does have one. (also apparently it is also a psychedelic...i didn't know that)
