To be honest I don't have the complete answer. Further, I feel uneasy legalising everything. But, not having the answer does not invalidate my view that the current approach is not working. It clearly isn't. An open debate devoid of emotion and politics is required.
Well it is likely to be a encroachment of legalisation, which for me is a sure way to increasing the usage of the drugs, however I am not sure a more puritan/anti approach would help.
I have not got any inclination to 'hit' those that choose to smoke the odd spliff and I recognise the contradiction regarding alcohol and nicotine, I am a regular user of alcohol !!
But as any responsible parent/government, we exaggerate to our young the pitfalls of many things we might have done or do ourselves, it offers balance to a difficult issue.
I dont care whether a habitual marijuana user demands legality or the puritan zealot demands deeper penalties, smoke your pot if thats your thing, maybe even toot your cocaine if thats your thing too, but you cannot make drugs more accessible, it might help the addicts, but it would only exacerbate the problem for us all.
