I'm not sure what the Supreme Court considers the definition of orginized religion. I know there are certain qualifications to be met so that a religion can meet certain tax-exempt status's (statusi?), but I don't know if those are the same in this instance.
As far as the drug thing goes, for the most part, it's illegal. Because the drugs are considered illegal becuase of they're considered a public safety hazard, they would still be arrested and charged. The laws against cannabis weren't made because of any kind of religious considerations, so that's usually not taken into consideration during trial. One notable exception is peyote. There are some native american indian tribes that are allowed special exemptions to use peyote during religious ceremonies, but that's strictly regulated...
