meh the whole system is crooked as shit,I think everyone ought to be able to grow cannabis, and those who choose, to use it medicinally. Even so... That doctor should lose his/her medical license, IMHO. Used car sales appears to be the profession that the person is more suited for.
the problem they have is, they lost control of the law schools, so within 5 years pot would have been recognized as legal to grow without conditions. All this licence stuff, except when it comes to resale, is just colour they are using to try to keep things under control.
but ya some doctors are shady (see opium epidemic)
