If you take a psychoactive substance (drugs, alcohol), you will experience its effects.

But did you know these effects are influenced by factors other than the substance?
That’s because of the law of effect.

Choose Your Experience

Everyone’s experience is unique. If you choose to use, check yourself first.

Begin the experience

FIRST TRIP AT A FESTIVAL?

I'm wondering

A festival can quickly become ultra-stimulating and a little stressful. Start with a small amount, try to keep your friends close, and remember to plan your way home in advance.

VODKA TO WASH DOWN YOUR PILL?

I'm wondering

Mixing substances is unpredictable and riskier (e.g. MDMA can mask the effects of alcohol). If you choose to mix, you can cut down the quantities, take one substance at a time and use water, instead of alcohol, to swallow your pills.

A FEW SHOTS TO FORGET YOUR EX?  

I'm wondering

Alcohol can accentuate the emotions you’re feeling before you consume it. You could start with a shot and wait to feel the effects before taking more.

Plan your trip

Before

01

Tell someone you trust about the substance you’re taking and ask them to check in on you after a few hours.

02

Try to determine in advance how much you plan to use.

03

Be sure to eat a few hours before consuming.

04

Try to get some rest. If you didn’t sleep well last night, or if this is your third party in a row, the drugs can hit harder, and the effects may be unexpected and potentially unpleasant.

05

Plan your return. How will you get back? Who’s with you? Where will you sleep? Do you have enough money for a cab? Is your phone charged enough to find a way home?

06

Make sure to have naloxone on hand. Learn how to use it and make sure your group of friends knows how to administer it:

07

Have any substances from the unregulated market analyzed. If it’s available near you, use a drug-checking service. It’s free and confidential.

during

01

Try to stay continuously hydrated before, during and after the event with water and/or electrolyte drinks.

02

Remember to cut your dose: start with a smaller amount and wait until you feel the effects of the substance before taking more.

03

Mixing substances can be highly unpredictable and carries increased risks. For example, MDMA can mask the effects of alcohol, leading to potentially dangerous situations. If you do choose to mix substances, consider reducing the quantities and taking them one at a time to minimize risks.

04

If you’re feeling unwell, talk to someone you trust.

After

01

Try to set aside time to rest and take care of yourself.

02

Eat well and stay hydrated with water and/or electrolyte drinks.

03

Ask yourself questions related to your experience. What did you like or dislike? What would you do differently?

04

Have your substance analyzed (if the service is available in your area) if the effects you experienced weren’t what you wanted. It may have contained unexpected molecules.

05

Don’t hesitate to talk about your experience with a professional or people you trust, even if it went really well!
