I'm not sure which way things would go if drugs were legalised.
Yes, the best outcome would be the removal of drug dealers whose raison d'etre lies in making lots of money out of encouraging the weak-willed to become addicted to drugs. That would be a good thing, of course.
What I'm not convinced about, though, is that if drugs were as freely available as tobacco and alcohol are at present, would that in itself encourage the same weak-willed to experiment. If that resulted in an increase in drug use, it would be almost as bad although, of course, drug barons would not be getting rich at drug users' expense. I suppose the government would reap the benefits in additional taxation!
So its just the weak willed who dabble with drugs...... hmmm.... i dont think thays right in any way shape or form.
I'd like to think that, if drugs became legal, there could be some way of discouraging their use. Unfortunately, I can't think what that might be.
