I don't want to pick a fight here but Cockswain, but whether you acknowledge it or not, what you did was stupid and dangerous, and chances are the cop was justified in pulling you over. You clearly have a vendetta against the police force (which isn't very uncommon) and you're using that to attempt to justify your actions to yourself, which isn't surprising because you often have a lot of problems admitting you're wrong (countless topics you fight with people over things you do that they disagree with (rightfully.))
When I used to drink, half the time I didn't recognise/acknowledge how drunk I really was, and I've seen a lot of other people in the same position. Chances are that you were the one in that position, and you had someone along with you who was only enabling your behaviour because it wasn't really affecting his life... actually, he was probably enjoying it, unless he was high too, and if that's the case he wasn't in any position to tell you that you were driving fine. If you had been in an accident and he had been hurt, I doubt he would've said "... no you were driving great I don't know what happened..." rather than "you were high as heck and driving crazy and nearly got me killed."
You're not going to accept responsibility for your actions, of course. You'll continue making excuses to make you feel like what you did was fine, but it wasn't, and even if you won't admit it, you should take what people are saying to heart so that you don't end up hurting someone else or yourself through your reckless actions in the future.
