some people have cannabinoid receptors and some dont. the ones that dont..... hate marijuana. often those types sit on the other side of a desk, some like to impose their ideals upon others. Political types, peole that wanna be cops, judges... are oft born without those receptors. I've known doctors that used mj regularly, cocaine and dilaudid too. Doctors are tyring real hard to break free of big pharma, but its hard. 'It is difficult to get a man to understand something, when his salary depends on his not understanding it.'
