They use it in SERIOUS medical conditions, such as cancer and glaucoma.
And it's not used to cure the condition, it's used to ease the symptoms, and promote appetite.
And plus, medical marijuana doesn't have over-concentrated levels of THC, like the weed that people smoke for recreational purposes, does.
So, therefore, it doesn't overstimulate the THC receptors in the brain, it causes less damage to your health, and is being used appropriately.
But I'd doubt anyone on this forum would be using weed for legal purposes, because, not only are the medical conditions rare, but it's even rarer that a physician will prescribe medical marijuana.
