“Smoking weed helps patients give up opiates such as heroin, a new study has found.
Researchers at Columbia University monitored patients undergoing treatment for opiate addiction – and found that patients who smoked weed were more able to sleep, less anxious, and more likely to complete their course.
The researchers also found that dosing patients with dronabinol – a drug consisting of the ‘active’ ingredient in cannabis, THC – helped with withdrawal symptoms.”
