First off, I am in Canada, so American Federal laws don't apply. Second off, yes controlling the temperature will make a difference. THC is what makes you "high" and is usually released when you combust (AKA burn with a fire). If you vaporize, with a controlled temp, you can have the weed release more CBD rather than the THC. I know FIRSTHAND from experience, not reading stuff online. When I use my vaporizer at a temp of 325F I don't get high, but it kills my pain, for hours
Okay fair enough you live in Canada and you don't have to be worried about American federal laws. The same applies for Canada as the doctors receive no schooling about cannabis use as a medicine in school. So like I said taking it to your doctor is not the best thing because he is not going to know anything about it unless he is a doctor that actually prescribes cannabis and has studied on his own time. Doctors from America or Canada go through very similar medical school. I can understand if you're going to your doctor to get it prescribed so it's legal but as far as asking his input is like asking him about some dietary supplement that he knows nothing about because he never learned it in school.
Now you say by controlling the temperature you don't get as high but what type of Strain are you vaporizing? Is it a high CBD strain that has low THC? Here's a fact for you, CBD vaporizes at a higher temperature than THC. So by you saying that you are vaporizing only the CBD because your temperature is set low is impossible. Truth be told THC has the lowest melting point of all of the cannabinoids.
Here are all the melting points and Specific boiling points and roles of cannabinoids
Δ-9-tetrahydrocannabinol (THC)
Boiling point:157*C / 314.6 degree Fahrenheit
Properties: Euphoriant, Analgesic, Antiinflammatory, Antioxidant, Antiemetic
cannabidiol (CBD)
Boiling point: 160-180*C / 320-356 degree Fahrenheit
Properties: Anxiolytic, Analgesic, Antipsychotic, Antiinflammatory, Antioxidant, Antispasmodic
Cannabinol (CBN)
Boiling point: 185*C / 365 degree Fahrenheit
Properties: Oxidation, breakdown, product, Sedative, Antibiotic
cannabichromene (CBC)
Boiling point: 220*C / 428 degree Fahrenheit
Properties: Antiinflammatory, Antibiotic, Antifungal
Δ-8-tetrahydrocannabinol (Δ-8-THC)
Boiling point: 175-178*C / 347-352.4 degree Fahrenheit
Properties: Resembles Δ-9-THC, Less psychoactive, More stable Antiemetic
tetrahydrocannabivarin (THCV)
Boiling point: < 220*C / <428 degree Fahrenheit
Properties: Analgesic, Euphoriant

And I will state again I am not trying to give you a hard time but I feel like there is so much bro science that is associated with cannabis because it has not been studied like it should have been.
