Smoke inhalation by igniting dried Cannabis flowers, leaves, stems, or — by contrast — by igniting dabs (shatter, budder, oil, live resin, and wax) is one of the most popular ways to consume THC (Tetrahydrocannabinol). Vapor inhalation, typically carried out by using a vape pen, is rather popular as a way to take in CBD oil (Cannabidiol).
Inhaling Cannabis can be done by using cigarettes, pipes, paper-wrapped joints, dabbing rigs, or a water pipe aka bong, among other equipment. But to be clear: both CBD and THC can be consumed via either vaping or smoking.
Consuming CBD or THC via vaping or smoke inhalation results in a quicker absorption of Cannabinoids in the bloodstream, and as such it causes a faster effect. Nevertheless, inhalation may have a risk of damaging the lungs and causing chronic lung disease (such as bronchitis).
Another risk is the inhalation of heavy metals due to Cannabis plants that absorb heavy metals from soil or contaminated irrigation water, and/or heavy metal leaching from vaping equipment. Inhalation of heavy metals can increase a user’s risk for cancer, neurological, renal, cardiovascular, and hepatic issues.
In any case, the effects after inhaling Cannabis can be felt within seconds to a few minutes, while the peak can occur within 30 minutes. Effects may last between 6 to 24 hours. Mind that inhaling too much THC at one time can lead to over-intoxication.
