In my view the fact that drugs are illegal does not stop people taking them. If anything it makes people want to take them more, as it's a feeling of doing something they're 'not supposed to be doing'. I get your point. I just don't think the consumption of drugs would change very much were they...
People are doing that anyway. People will always take drugs no matter what so criminalizing it is not the answer. It still baffles me that alcohol is deemed fine when in reality alcohol is just as damaging if not worse to people's health and behavior than many drugs.
