A lot of people are unaware that anyone's Religion in America has Freedoms apart from Christianity. In fact, some people don't even believe other religions exist, even religions that are 12% of Earth's population. If you have never heard of "Shiva" he is worshiped by certain groups of Hindus and Certain groups of Buddhists. He is also worshiped in his "pre-Shiva" form, which is "Rudra". So if we get into all of Shiva's forms, it could be more than 12%. But Shiva himself is worshiped by 12% of the planet.
Here are what India calls "Sadhu"s, they worship Shiva by smoking Marijuana or Hash out of a pipe or paper, but usually a "Chillum" pipe. They wear Rudraksha beads to represent Rudra and the Smoke Marijuana to Represnt Shiva. I do the same. Just because I am in America, does not mean my religion does not exist. I was arrested in Texas for this and they acted like ther ewas no way my religion could possibly involve Marijuana. But I was also 14 and 17 when these happened, so it's not their fault, they just didn't want to listen to a kid. But they were and are dead wrong.
