Today, you can find them everywhere in corporate America.
Tattoos are cool and hip, to some. Most of the younger employers have them too. When I was younger, and I assume for you also, tattoos were for bikers or mechanics. Girls didn't have them unless they were hookers in training, today women have them because they are cute and trendy (until you start to sag and wish you never dumb enough to let someone tattoo you).
As for weed and presidents, the media and state politicians have made it so mainstream that it isn't seen as the gateway to hell anymore, but I think that's a result of education more than ignorant acceptance. Remember past monarchs were also cannabis users, it wasn't until the US made it illegal and media jumped all over it with smear campaigns about losing your mind and killing people, that it was opposed to begin with.
Now people are waking up and realizing it's not the end of life to smoke weed for recreation and within reason. In fact, the legal drug Alcohol kills people every day, ruins families, creates crime etc. Weed can only be attributed to such issues if it is seen as a gateway drug.
Gateway drugs are only a gateway for people WITH existing problems who will constantly seek other ways to get rid of internal, mental pains and troubles. If it wasn't weed, they'd go straight to alcohol and THAT would be the gateway drug.
