Wild lettuce is useful to quit tobacco &/or cannabis, as a replacement therapy. The Hopi Indians smoked the dried leaves and the roots of wild lettuce to intensify their dreams. Wild lettuce is known as poor man’s opium, it’s considered milder than poppy opium, but just as dreamy without the risk of addiction. It may assist in opiate withdrawal, rather than methadone which is addictive and some consider more damaging than heroin itself.
