FREQUENTLY ASKED QUESTIONS ABOUT CANNABIS

Recreational cannabis became legal in Canada on October 17th, 2018, under the new Cannabis Act. Despite being a federal law, it grants provinces the authority to impose certain restrictions within their territories regarding cannabis use. These restrictions vary, covering factors like the minimum age for consumption and the permissibility or prohibition of cannabis use in public spaces. Given the potential differences in regulations from one province to another, it’s essential to be aware of the specific rules that apply to your location.

Canada is the second country globally to legalize recreational cannabis. However, with this legalization comes a myriad of questions, many of which may pertain to health and safety. Fortunately, your pharmacist is well-prepared to navigate this new reality and address any inquiries you may have.

There have been no deaths attributed to cannabis overdose, as it is close to impossible to ingest a lethal dose. However, consuming a large amount is not recommended.

WHAT’S THE DIFFERENCE BETWEEN SMOKING CANNABIS AND EATING/DRINKING FOODS CONTAINING CANNABIS?

The chemicals in cannabis are absorbed differently depending on how it is consumed. When smoked or inhaled, cannabis’ effects appear faster, but are shorter in duration. When ingested, the effects last longer and are much stronger.

SHOULD I BE AWARE OF ANY PRECAUTIONS WHEN USING CANNABIS?

Family planning, Pregnancy, and Breastfeeding: Cannabis should be avoided during pregnancy or breastfeeding, as the chemicals in cannabis can pass through the mother’s blood to the fetus and into breast milk, potentially causing developmental effects in the baby. In men, chronic and long-term cannabis use may decrease sperm count and motility.

Driving: Similar to drinking and driving, operating a vehicle under the influence of cannabis is against the law due to its sedating, psychoactive, and physiological effects. Penalties for drug-impaired driving can range from fines and license suspension to a criminal record.

Traveling: Within Canada, travelers can carry up to 30 grams of cannabis for personal use, including passengers on domestic flights. However, it is prohibited to transport cannabis across international borders.

Health Conditions: Whether used for medical or recreational purposes, cannabis may impact your health and existing medical conditions. Consult with your healthcare provider to better understand the potential effects of cannabis on your health and receive an unbiased opinion.

DOES CANNABIS INTERACT WITH OTHER SUBSTANCES?

Alcohol 

Cannabis and alcohol use have some similar effects. If taken at the same time, their effect can combine, be stronger, last longer and could lead to potential accidents. If drinking responsibly is important when consuming alcohol, it is strongly not recommended to combine the two substances.

Medication 

Cannabis can interact with many drugs, over-the-counter medicine and natural products. Talk to your pharmacist today to review your medication for potential interactions.
