Smoking cannabis (a joint, pipe or bong) is the most harmful way you can use cannabis because it directly affects your lungs.
Options like vaping or consuming edibles may be less harmful for your lungs but can still cause harm. Keep in mind that these alternatives can also affect your health in other ways. See the Health Unit’s September 2019 Health Fax for the latest information related to the health impacts of vaping.
If you choose to smoke cannabis, avoid inhaling deeply or holding your breath, as these practices increase the amount of toxins absorbed by your lungs.
