Why is the CANDIDE study being done?
We are studying the effects of cannabis and tobacco use and secondhand smoke exposure on vascular function.
There is widespread belief that, unlike tobacco smoke, cannabis smoke is benign. While the psychoactive substance in cannabis is tetrahydrocannabinol (THC) rather than nicotine, cannabis smoke is still the result of burning plant material and contains many of the same thousands of chemicals as tobacco smoke, including fine particles that cause cardiovascular disease and death. However, due to the prior illegality of cannabis, it has been difficult to study the harmful effects of cannabis smoke, and the few secondhand smoke (SHS) studies have focused primarily on whether people exposed to SHS risk testing positive on drug tests. The increasing number of states legalizing medicinal and recreational cannabis make it important to understand the public health consequences of both active and secondhand exposure to cannabis smoke.
