After selling drugs to a customer or taking them yourself, you might notice some noticeable changes, some enjoyable and others not so much. These effects can range from boosting your speed, gaining weight, or even changing your gender, to something as extreme as exploding. If you’re curious about how many effects are listed in Schedule 1 and what each one does, this guide has got you covered.
All Effects in Schedule 1 and what they do
Below are the effects listed in Schedule 1 and how they impact NPCs or, even, your own playable character. These effects can also stack, but each one only lasts for a few minutes before it expires.

In Schedule 1 players will likely come across a total of 35 different drug effects. So plenty of experimenting and working out which ones you want, or, even, don’t want.
- Anti-gravity: Allows the user to jump higher than normal.
- Athletic: User gets to run 30% faster than normal. Ideal when escaping police, or delivering drugs

- Calming: Chromatic aberration will appear around the screen
- Calorie-Dense: User will appear fat
