yes ur right that combustion is the carcinogenic part, however most people smoke weed...so its a valid consideration.statistically barely anyone uses a vape.. and again i agree that it depends on the individual, but weed is a catalyst so that must also be taken into consideration. look all im saying is that yes you should be allowed to take in any substance you like, its ur body. however, consistently telling people that weed has 0 problems is incredibly misleading and i think hurts the overall argument for people having free choice on what they take. also when i have people telling me it cures cancer, that irrelevant to the stage 3 patient who NEEDS chemo. i have so many people on fb telling me to screw chemo and just go for an all natural approach. this, i find is incredibly stupid. in regards to short term memory loss, sure its only temporary, but when u blaze all the time ur short term memory never has a chance...
