Methylphenidate, the drug I take to contain my ADHD, is supposed to be similar to cocaine. Overdosing on Methylphenidate, I’m told, produces the same effects on the mind that snorting cocaine would, because of which it is a tightly controlled drug. It is available only in two pharmacies in Bangalore, and they stamp your prescription with a “drugs issued” stamp before giving you the drugs.
Extrapolating, and referring to the model in my post on pot and ADHD, snorting cocaine increases the probability that two consecutive thoughts are connected, and that there is more coherence in your thought. However, going back to the same post, which was written in a pot-induced state of mind, pot actually pushes you in the other direction, and makes your thoughts less connected.
So essentially, pot and cocaine are extremely dissimilar drugs in the sense that they act in opposite directions! One increases the connectedness in your train of thought, while the other decreases it!
I’ve never imbibed cocaine, so this is not first-hand info, but I’ve noticed that alcohol when taken in heavy doses (which I never reach since I’m the designated driver most of the time) acts in the same direction of cocaine/methylphenidate – it increases the coherence in your thoughts. Now you know why junkies in your college would claim that the kind of “high” that pot gives is very different from the kind of high that alcohol gives.
