The approach of drugs in America is quite complex, I believe that to take a step forward in the legalization of marijuana the federal government and other related institutions have to recognize and accept certain errors in their approach to the war on drugs.
They concentrate only on punishing the traffickers, but this situation will not change if your population is the largest consumer in the world, the demand is huge.
In the case of marijuana, it seems to be still a taboo, although the income generated by this industry is not very high compared to others, it will be very beneficial because it reduces expenses of certain government agencies and collects taxes from commercial marijuana activities.
At the regional level the progress has been good but at the federal level the situation is a bit more complicated, although the Democrats are the majority in the congress, I think that this issue would not be so important.
I believe that even the Democrats are the majority in the congress this issue would not be so important for them.
Great comment. I think you have a good understanding of the scheme here.
