Not knowing the exact substance name should not stop you from seeking help. The first question is the person’s current condition and whether urgent care is needed. Discussion can then cover use history and changes in everyday life.
What "psychoactive substance" means
It is a broad term: it covers illegal drugs, some prescription medicines and alcohol. One distinction matters: the word "psychoactive" does not by itself mean that a substance necessarily produces dependence.
The main groups, in plain language
Below are the main groups that medicine distinguishes. The list covers the main groups, not every substance that exists.
Opioids. Heroin, morphine, methadone, tramadol and other prescription painkillers. They relieve pain and anxiety but slow breathing, which is why an overdose can be fatal.
Synthetic opioids. Fentanyl, nitazenes and similar laboratory-made substances that are many times stronger than heroin; they are often present in other products without the buyer knowing.
Stimulants. Amphetamine and methamphetamine, cocaine, and the synthetic cathinones (mephedrone and others) sold as "salts" or "bath salts". They produce alertness and energy but strain the heart and blood vessels, and with prolonged use can cause paranoia and hallucinations — stimulant psychosis.
Sedatives and benzodiazepines. Medicines for anxiety and insomnia (benzodiazepines, sleeping pills). Useful when prescribed, but prolonged uncontrolled use leads to dependence, and stopping abruptly is medically dangerous.
When use becomes a problem
Not all use is dependence. In medicine, a diagnosis of dependence — a "substance use disorder" — rests on a defined set of features. In plain language they fall into three groups.
- Loss of control. Using more, or for longer, than intended; attempts to cut down keep failing; strong desire (craving).
- The substance takes priority. A lot of time goes on obtaining, using and recovering; obligations at work, in study or in the family suffer; things that used to matter are given up.
- Continuing despite harm. The person knows that use is damaging their health, relationships or finances and continues anyway; uses in risky situations (for example, before driving). The physical features belong here too: tolerance (the old dose no longer works) and withdrawal when use stops.
Why different substances call for different medical caution
Behind the general word "drugs" are substances whose risks are very different in nature. A few examples.
- Sedatives and alcohol: stopping can itself be dangerous. Alcohol withdrawal can range from tremor and sweating to seizures and delirium; a proportion of people with an alcohol problem need medical monitoring for exactly that reason.
- The risk rises sharply when an opioid is taken together with alcohol or sedatives, and after a break in use, when tolerance has fallen. Naloxone, given in time, prevents death from opioid overdose.
Life-threatening situations
If after using a substance a person cannot be woken, their breathing is slow or interrupted, their lips are blue, they have had a seizure, or there is severe chest pain, very high temperature, or sudden agitation with confusion — call 103 (ambulance) or 112 (unified emergency service) immediately. Do not leave the person alone and do not wait for them to "sleep it off". The booking form and the reception phone are not for emergencies.
Your next step with MMS and MIDAS
A free initial rehabilitation consultation at MMS can explore the situation and your next support needs. Suitability for MIDAS by MMS is considered separately. If the substance is unknown, say what you know without presenting a guess as a confirmed fact.

Questions
Is a street name enough?
No. It cannot reliably establish the composition or the person’s condition.
Does one episode mean addiction?
Not automatically. Risk, consequences and ongoing patterns need professional assessment.
What if I do not know where to start?
Tell reception you need an initial rehabilitation consultation and explain your concern.
