Three years ago we had to develop an eLearning course, to be used by the UK government for training what they call first tier response staff (police, clercs, pharmacies, etc., so we had to do a lot of research. They also had their own.
My point is that:
- the amount of deaths in the UK over the past 50 years shows zero deaths caused by weed. Both direct and secondary causes. Alcohol and tobacco on the other hand have caused millions of deaths, both direct and through accidents. Weed is not the same as the other two - it's a huge misconception to compare them at all.
- If you smoke weed 4-7 or more times a day you have a problem. I'd say if you eat meat that many times you'll also have a problem. Anything can be very dangerous if you have no limits, that's not the point here :)
If you really want to check, take half an hour and find some stats for weed-related health problems and deaths, not essays and opinions, statistics. You won't find much such cases, if any, anywhere in the world.
I agree about the influence on kids, this should be persecuted.
