How TakeSafe works — and what it doesn’t do
TakeSafe helps reduce avoidable harm by showing how substances interact over time.
It visualises when effects start, peak, overlap, and wear off — so higher-risk combinations are easier to spot.
What TakeSafe does:
- Shows timing and overlap of common substances and medication classes
- Highlights higher-risk overlap periods
- Uses evidence-informed sources and states uncertainty where evidence is limited
What TakeSafe does not do:
- Promote drug use
- Provide dosage advice
- Replace medical or emergency care
Clear information reduces harm. Uncertainty should be stated, not hidden.

TakeSafe is designed for people checking safety before, during, or after substance use — and for friends supporting them.
