Simple solution: require all alcohol users to be LICENSED in order to buy or possess or use.
No license no sale, no buy, no use
ALSO
if you have an alcohol user license then you are forbidden from having a driver’s license of ANY kind. (CDL, DL, motorcycle, etc)
one joint and you are incapable of legally driving.
not so with alchol. We are talking about pot, not red herrings.
PS: we already have DWI law regarding impairment and specifically for alchol content based on the chemical action of such liquid.
Pot is instantly incapacitating. Just look at the you tube videos and contless articles which show how post impairs visual and physical acuity with artistry.
