Alcohol and recreational drug use

Excessive alcohol consumption

Drinking too much of any type of alcohol can increase your blood pressure and contribute to the development of heart disease and stroke.

If you drink alcohol, limit yourself to no more than:

  • two drinks a day most days, to a weekly maximum of 10 for women.*
  • three drinks a day most days, to a weekly maximum of 15 for men.

“A drink” means:

  • 341 mL / 12 oz (1 bottle) of regular strength beer (5% alcohol).
  • 142 mL / 5 oz wine (12% alcohol).
  • 43 mL / 1 1/2 oz spirits (40% alcohol).

* Do not drink when you are driving a vehicle, taking medications or other drugs that interact with alcohol, pregnant or are planning to be pregnant, making important decisions, doing any kind of dangerous physical activity, living with alcohol dependence or mental or physical health problems, or responsible for the safety of others. If you are concerned about how drinking may affect your health, talk to your doctor.

Recreational drug use

Using these recreational drugs can increase your risk of having a stroke and developing heart disease:

  • amphetamines
  • cannabis or marijuana
  • cocaine
  • ecstasy (MDMA)
  • opioids
  • LSD (lysergic acid diethylamide)
  • PCP (phencyclidine)

The risk of having a stroke is six times higher in drug users than non-drug users. And, in many cases when a stroke occurs, it happens within hours of drug use.
