Having spent over two years on the Washoe County Grand Jury, I've been amazed at how disproportionate the law is compared to the actual physical and social damage resulting from the use of each type of drug.
Apparently others agrees - details here.
Even this chart has a muted range when applied to an individual. In the cases I've seen, the curve's far steeper on both ends with meth at the top. Do solvents REALLY do less social damage than cannabis?!?! Certainly not if you're the one huffing.
I can only assume they were measuring TOTAL social impact as opposed to individual social damage, since the incidence of solvent abuse is far more rare than cannabis. Of the 12 million monthly users in America, ever hear of anyone over-dosing on marijuana?
In any case, it's good these drugs are finally being painted with separate brushes. From all the studies and history, our laws are obviously upside-down - especially when it comes to alcohol and cannabis.
Let's get real with the science and the law, before more kids decide they have to try ALL of these things just to learn the truth. Remember that chant from the 60s?
Let's start telling it like it IS!
