The regulated legalisation of all recreational drugs will save the world. At the moment the illegal drug trade is making a few king-pins very rich while the rest of us are excluded from the benifits of this highly lucrative industry. Regulated legalisation would be a boon to all members of society as national governments reap the tax revenue from their legal production and sale (look up Jeffrey Miron for an economic analysis of a legal recreational drug industry).
True, any form of drug taking has health consequences, but there are also benefits, and to deem illegal drugs as wholly detrimental is blinkered, as many an insomniac pot user will attest, it is safer and more effective than benzodiazepan or other sedatives, and it only takes one cup of coffee in the morning to feel bright and chirpy while the 'hangover' from legal medications can last all day.
For those of you interested I recommend the Transform Drug Policy Foundation's website for a rational and reasonable analysis on how a regulated and legal recreational drug system can work.
Legalise it so the tax revenue can benefit us all, not just Pablo Escobar, Joaquin "Chapo" Guzman and their ilk.
