I find this highly unlikely, psychosis and schizophrenia for example results in increased suicide rate. Whilst noone may have died of cannabis overdose people would have died from secondary effects. How many Americans killed in road accidents during that period were found to have cannabis in their bloodstream for example?Quote:

This paper indicates that the risk of male specific cancers is increased in male cannabis users.
As do heroin addicts as they use any available income for drugs and neglect to eat.Quote:

There is a definite link between cannabis and psychosis/schizophrenia although you are right, it may be that those who are predisposed to those conditions are more likely to be cannabis users. If this is the case do you think its right that those who are vulnerable to such problems are drawn into drug use?Quote:

The above paper however is interesting as it demonstrates that cannabis has a definite effect in the production of an enzyme that metabolises dopamine, disturbances of which are found in schizophrenia.
Many of your points downplaying the health risks of cannabis are wrong and smell of someone reading straight from pro-cannabis literature. However I do agree with you that there is an argument for the legalisation of cannabis and some other drugs on the basis that it denies the criminal element a source of income and the quality of drugs can be checked. Taxation levied on the drug can then be used to pay for the health consequences which happen anyway thanks to illegal drug use.Quote:

That said one should also remember the effect British exports of opium had on China with reduced productivity and increased corruption as young men spent all their days under the influence of the drug, which is why China banned it leading to war with the UK.
