To anyone that uses drugs –
The drugs available in the UK seem to be changing lately. New opioids have arrived in the UK in the last two years, called "nitazenes". They have recently been found mixed with heroin, with some being sold as illicit oxycodone pills or even Xanax powders. They have also been found lacing other popular drugs such as benzodiazepines, cocaine, ketamine and synthetic cannabinoids (spice).
Nitazenes can be at least as strong as fentanyl and can be hundreds of times more potent than heroin. They are known to have led to accidental overdoses and deaths of people in several areas across the UK in recent months.
The vast majority of people taking drugs do not expect to die from an overdose. If you use drugs, this information will help you and your friends to stay alive.
Considering new information around contaminated drugs, the way you use drugs might need to change to avoid overdose:
Mixing different drugs is common, but it is more likely to cause an overdose. Try to use one at a time. If you are going to mix drugs, use less of each.
Try not to use drugs alone, and don’t let your mates use them alone either. Watch out for signs of overdose in your friends. The signs include difficulty breathing, blue colouring to the lips or fingertips, unresponsiveness, and limp limbs.
If using drugs that you are not certain of what’s in them- Always carry naloxone. It’s available from all treatment providers. Our local drug and alcohol service Change, Grow, Live (CGL) in Brighton can provide these anonymously, and show you how to use them.
If someone overdoses, give naloxone to them and call an ambulance. Naloxone does not entirely cure an overdose, but it does buy time for more help to arrive.
Naloxone only works on opioids. However, if you suspect someone has overdosed give them naloxone even if you’re not sure they have taken an opioid. It will not harm your friend.
If you use opioids every day your local drug treatment service can support you and prescribe alternatives such as methadone and buprenorphine. Even if abstinence isn’t your goal these alternatives can help keep you safe. You will know what you are taking and your risk of overdose may be reduced.
If you feel like you have a problem with alcohol or drugs, contact your local drug and alcohol service (Change Grow Live), or alternatively, refer in to our therapy service for confidential support on campus.
