We have too many Americans behind bars on drug charges. We know in many cases people get injured and need pain relief.
What is reasonable? A man in California was killed in a train collision. The engineer at the time of the collision was under the influence of marijuana. Clearly, we need strict and clear laws on operating heavy machinery or operating a vehicle.
What an American does in (possessive pronoun) that does not harm others should be legal.
What can I do to help?
