That brings up another interesting situation.

Lawyers, and other public services, have to sell themselves in order to gain success. They don't want the Judge thinking they they smoke Herb, nor do they want their clients.

Maybe, in 100 years, the general population will want doctors who smokes joints with their patients before surgery.

Getting high allows a great deal of information to enter your head, at once. Therefore, never, will people want a Lawyer who'll get high before court.
