Sounds like the California "medical marijuana" scam.
How have the tenets of California's medical marijuana movement been refuted by outcomes of their implementation? Are sick people using doctor-recommended marijuana and deriving no benefit?
The scam was sold to the public as a means for a handful of seriously ill patients to have their "primary caregivers" grow small amounts for them. It's turned into dope dens calling themselves clinics selling designer dope for hundreds of dollars an ounce to 150,000+ potheads claiming to have symptoms like insomnia or a headache.
