Why is this news? If not already done, just extract the active ingredient in the weed, and take the pills. That would be much safer than ingesting and exposing to others all of the tars and carcinogens in the smoke.
Why do the legislators pushing for "medical marijuana" not know this?
Pills are slow-onset, so it's difficult to adjust the dose to the minimum required at the time (aka titration), and are hard for nausea patients to keep down.
That would be much safer than ingesting and exposing to others all of the tars and carcinogens in the smoke.
Using a vaporizer would avoid the harms due to smoke.
Aren't these matters that should be decided by a doctor and patient, and not by the government?
