Nitazenes are a group of synthetic opioids that have been widely detected in all parts of
Scotland. Different types have been identified. Some are hundreds of times stronger than he**in.
Nitazenes are most commonly found as a contaminant in drugs sold as he**in, benzodiazepines
and oxycodone.
Overdose can happen quickly and unexpectedly.
Overdose signs might include:
• being unresponsive (will
not wake when shaken)
• snoring or noisy breathing
• blue or pale lips
and skin
• seizures or fits.
• Naloxone is a medicine that
can temporarily reverse
opioid overdose. It should
be given to anyone who is
unresponsive and showing
overdose signs.
• Naloxone can reverse the
effects of nitazenes, but
repeat doses may be needed.
Doses should be given one
at a time, two to three
minutes apart.
Harm reduction
Follow opioid harm reduction advice, with greater caution
due to the risk of contamination:
• Use drugs in the company of other people, and take
turns to dose.
• Avoid mixing drugs knowingly, including alcohol
and medicines.
• Dose low and go slow. Take a smaller amount than you
usually would and leave a long gap in between doses.
• Get naloxone from your local drug service or order
from www.sfad.org.uk
