Some employers now will not let cigarette smokers work for them, even if they only smoke when off the clock and off of company property. These policies have been challenged in the courts, and the employers have won. If employers don't want to hire pot smokers, they won't have to whether marijuana is legal or not.
The stigma that marijuana really isn't there because it is illegal. It's there because people have no respect for forty year old stoners who live with their parents. It's there because there is nothing cool about being one of the stoners sitting on the couch stoned out of your gourd staring at the TV with the sound turned off, a scatterbrained stoner who makes no sense half the time. There are so many good reasons not to be a pot smoker, especially one who smokes it all the time. Whether it is legal or not, there will always be a stigma associated with smoking pot. Parents won't want their kids to smoke it. Most young ladies will not want pothead boyfriends, like most wives don't want pothead husbands. A lot of people will not like it being smoked in their homes. It's just not the fun social lubricant that alcohol is most of the time and it will never enjoy the popularity as alcohol, and it will always carry with it a certain stigma.
Look at the Netherlands. Marijuana is for all intents and purposes legal there and has been since the 1970s. Retail sales from facilities with permits are legal. Possession of a small amount is legal. Growing a few plants is allowed. Most people don't smoke it though. Only around 20% of the Dutch have even tried it compared to over 40% of Americans. A much lower percentage of their teens have tried it compared to teens here. It's not really “cool” to be a pot smoker there. A young person who does it is no rebel, he's just one of the losers sitting on the couch stoned out of his gourd staring at the TV with the sound turned off. That's no way to be if you want to have any luck with the ladies. It's just not really cool there. I don't know what our fascination with it is but we almost always have the highest per capita use numbers and when ours aren't the highest no country has substantially higher use than we do.
The laws in place in a country or a state really don't seem to matter. Where marijuana is popular it is easily available to anyone who wants it and those who want to smoke it smoke it. We're a lot harder on pot smokers than most Western nations, yet we almost always have the highest per capita use rates. You see the same thing all over the Western world though. There is little correlation between the laws in effect and the per capita percentage of people who use marijuana. Some places have harsher laws and lot of people smoke it, while others basically allow it and far fewer smoke it there than in the places with more strict laws.
I honestly believe that the vast majority of people who would smoke marijuana in this country already smoke it. If all the good reasons not to smoke it not related to its legal status are not enough, the far remote possibility of getting caught and having to maybe pay a fine, maybe even be on probation for a while or whatever isn't going to stop these people. And those precious few who are waiting for it to be legal before they smoke it aren't going to be a problem for us. For one there aren't that many of them, and the fact that they are responsible enough and have the will power to leave it alone now indicates that they would probably be fairly responsible pot smokers. The real losers and trouble makers who would smoke it are already smoking it.
Thanks!
