legalize 'em all - just make penalties for misbehavior and mistakes while intoxicated rather dire and inescapable, and end all government funding and insurance liability for users (and I mean this for alcohol as well)
then... let fools perish and the cautious live as they will.
I would agree, along with the following conditions...
1. Mandatory drug testing for all paid employees of 501(c) tax-exempt corporations as a condition in the IRS Code to have non-profit status.
2. Mandatory drug testing as an Occupational Health and Safety statute for any employment in the United States.
3. Mandatory drug testing for any license to operate motor vehicles (including quads, motorcycles, etc.), aircraft and boats (or water craft).
4. Mandatory drug testing for any professional license.
5. Mandatory testing to maintain such licenses and as a condition for such, any accident investigated would require the signature of a waiver for consent to be tested before such a license is issued.
