Cannabis is one of the best treatments for ADHD, especially alongside a stimulant that is amp based.
I’m not a doctor, and I do not recommend combining it with SSRI meds, as that combo can impair driving.
It also depends on the strain used. We talk about cannabis like it’s just one drug. It’s not. The combination of different cannabinoids and terpenes in the strains make up thousands of different medicines. Each one has different effects.
Research the endocannabinoid system. Newly discovered, it is just as important as and works together with all of the other systems in the body.
Our bodies already make natural cannabinoids (example: anandamide, an endogenous analogue of tetrahydrocannabinol, or THC, aka endocannabinoids). Some people need exogenous cannabinoids to supplement (example: vaping cannabis).
It is healthy to balance the endocannabinoid system. Once research on this takes off (finally), it will change the way we think about medicine.
