Apologies for the delay in replying. The answer I received was that there was no particular branded product that was better than another. Most of the products contain a combination of what are termed Cannabinoids, referring to the different compounds found in cannabis. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis. Cannabidiol (or CBD) is another major constituent of the plant. Both CBD and THC are found in various combinations in the various products. Products with lower doses of active ingredient, especially lower THC were available over the counter in pharmacies, and higher concentration products usually require a doctors prescription. Most of the products are liquid “drops”, but some are inhaled. Following advice from her doctor my friend experimented first with the lower concentration products before finding a mid strength combination that worked for her. It’s funny how (if a thing doesn’t effect you) you have almost zero knowledge of it until you ask. The things people go through, sigh. I hope that helps your friend on some level.
Kind regards, Andrew
