Maybe, but I'm having a hard time to imagine a scenario where it is really easy. It is not that easy (as, say, soft drinks) neither in Uruguay or Amsterdam. It is expensive at the houses of everyone involved in drug dealing - it is their work after all.
Any way, the exceptions don't affect a open poll as this one. But I would be interest in a research that answer this questions at different realities, such as, slums, high society, drug dealers family, public high school, private high school, etc.
Why are you surprised? I don't feel like I'm missing out on anything and consider most people that do drugs to be pretty irrational (especially anything beyond the socially accepted alcohol and cigs).
> Seems kinda silly to think that "socially accepted" drugs make someone more rational than the non-socially-accepted drugs.
If something is socially acceptable then more people will try it because of group pressure. That's why I don't consider those to be as bad as stronger stuff. But in principle they are the same and alcohol is stronger than most soft drugs that are permitted in the Netherlands. Still doesn't seem to be outlawed in many places though...
No. Researchers use tricks to get people to answer honestly. For example: they ask people to toss a coin before answering. If the coin comes up 'heads' the person must answer 'yes' even if their real answer would be 'no'. If the coin comes up 'tails' they must answer truthfully.
The introductory text explains that there is no way to know if the person is answering truthfully or following the coin 'heads' rule.
When you get the results you adjust for probability of the coin toss.
