I agree. On that same point I think driving under the influence of Benadryl should be illegal since it is well known to cause drowsiness, and alertness is a critical component of driving. I'm also at a loss on why the legal status of any drug or substance should take driving into account, since the theory behind driving is that you should be alert when driving and there are plenty of legal ways to decrease alertness. It's just that people concentrate on mind altering ways to not be alert as opposed to using a cell phone or eating or putting on makeup or numerous other things people do behind the wheel, yet the idea of making those precursor actions (using a cell phone in general, putting on makeup at home or in a bathroom, etc.) is absurd. Yet for some reason the idea of making intoxication by itself on certain substances is widely celebrated. I fail to see the rationale behind the latter (or more accurately, I see the rationale but don't believe it is strong).
