Synthetic cannabis (spice): why it's more dangerous than it looks
A clear answer from the Restart team — reviewed November 2026.
Synthetic cannabis isn't natural cannabis — it's lab-made chemicals sprayed on plant material. The formula keeps changing and the strength is unpredictable, so it can cause racing heart, panic, seizures and psychosis — even on first use.
- It may be sold as 'incense' or 'herbs'
- It doesn't always show on standard tests
- Severe symptoms need emergency care
How is it different from natural cannabis?
The synthetic compounds bind brain receptors far more strongly, and there's no known 'safe' dose because every batch differs.
How is it treated?
After any emergency is handled, treatment rests on psychiatric assessment, CBT, treating any psychosis or anxiety, and relapse-prevention follow-up.
