1. The MW of THC is on the internet: 314.45 g/mol
DMT is in the Database.
I know someone who liked and recommended Aniracetam (Aniracetam is a fat-soluble molecule in the racetams family, anecdotally touted to be more potent than Piracetam and more catered to creativity and holistic thinking as well as reducing anxiety and depression)and that is in the Database.
2. According to two experts I've spoken to at length, one a Pot doc here in the states, the other a cannabis grower/researcher in Canada who's been involved in studies involving 8k people, you need to use oil made from the whole plant for working on cancer. Pot doc says you need both THC & CBD. There are strains which are low in THC (1/2 percent or so) and high in CBD which you cas. You also need the Terpines. Then there's a new line of information indicating that another component, CBG is the real powerhouse for healing.
I don't think you'd get high by running a freq for THC, but like Paul just noted, there are exceptions. You might actually think about running CBD, because that stuff works miracles on all sorts of things, especially inflammation.
