As a baptised J.W., I personally would not use any substance even if it were free. The exception is drugs prescribed by a G.P. As an ex-smoker, I am well aware of the habit forming chemicals in cigarettes. As to control, it seems that the Dutch government has the answer. Apparently in Amsterdam, marijuana can be bought from kiosks in the street. No one is forced to buy it. If cigarettes can be sold and controlled by government, why not other substances. And those who choose NOT to participate just don't. Availability seems to solve the crime aspect of drugtaking. And controls similar to alcohol and driving will ensure road safety. But for any government to bring the problem out into the open might seem as though they are condoning the practice. Yet the same governments condone alcohol and tobacco, both of which do not really help our health.
