Understanding cannabis safety means looking beyond the product you choose. Potency, timing, medications, and your surroundings can all affect your experience.
Whether you’re new to cannabis or have used it before, these considerations can help you make more informed decisions.
Effects Can Vary From Person to Person
The same cannabis product can affect two people differently. Your experience can depend on the amount of THC, your previous cannabis use, underlying health conditions, and whether you have consumed alcohol or other substances.
Cannabis can cause anxiety, panic, and difficulty concentrating. Higher THC levels can increase impairment and the likelihood of unwanted effects. A product that feels manageable to someone else may be too strong for you.
Pay Attention to Potency and Timing
Read the label before consuming, including the THC amount per serving and the total amount in the package. One package may contain multiple servings.
For adults who choose to consume edibles, Health Canada recommends starting with 2.5 mg of THC or less. Effects may begin within 30 minutes to two hours, but it can take up to four hours to feel the full effects. Taking more too soon can lead to an unexpectedly intense experience.
Inhaled cannabis acts more quickly, but the full effects can still take up to 30 minutes to develop. Give yourself time to assess how you feel before considering more.
Plan Transportation Before Consuming
Cannabis can affect reaction time, coordination, and judgment. Do not drive or operate machinery while impaired. Arrange transportation before consuming so you do not have to make that decision afterward.
Combining cannabis with alcohol can increase impairment. Avoid using them together.
Check for Medication Interactions
Cannabis products can interact with medications. CBD also carries interaction risks, even though it does not produce the high associated with THC.
CBD may increase or decrease the effects of certain medicines, potentially increasing side effects or reducing treatment effectiveness. Ask your pharmacist or healthcare professional about possible interactions before combining cannabis or CBD with prescription medicines, over-the-counter products, or supplements.
Consider Your Health and Method of Consumption
Smoking cannabis can harm lung tissue. Choosing an edible avoids smoke exposure, but introduces different concerns, including delayed effects and accidental overconsumption. No consumption method eliminates every risk.
Avoid cannabis during pregnancy and breastfeeding. If you are pregnant, planning a pregnancy, or breastfeeding, discuss cannabis use and alternatives for symptom management with your healthcare professional.
Notice Changes in Your Use
Pay attention if cannabis becomes difficult to cut back on, interferes with responsibilities, or replaces activities you previously enjoyed. These can be signs of cannabis use disorder.
If you are concerned about your use, a healthcare professional can help you assess what is happening and discuss support options.
Store Products Securely
Keep cannabis products locked away and out of sight and reach of children and pets. Edibles can be mistaken for ordinary food, and accidental ingestion can cause serious illness.
If you suspect a cannabis poisoning, contact U.S. Poison Control at 1-800-222-1222. Call 911 for an emergency, including difficulty breathing or unresponsiveness.
