"I'm 65 and overweight. Is their a cannabis product for pain, sleep and/or psycho-activity that does NOT stimulate the appetite?"
I find that Blue Dream and Cherry AK do not cause me to have an appetite. They are both Sativa dominants and generally have me feeling motivated to go complete a project, rather than hunkering down with some doritos and cheese dip.
THCV is a cannabinoid that has been found to increase energy and suppress appetite. Sativa's and Hybrids contain higher amounts of THCV- Durban Poison, Dutch Hawaiian, and Skunk #1 have been found to be the most common strains. These strains also contain a "faster" high, one that lasts shorter but feels more intense.
