The article explains why different drugs are dangerous and which signs require immediate help. If an overdose is suspected — loss of consciousness, shallow breathing, seizures, bluish lips — call emergency help (103) immediately.
Why some drugs are more dangerous than others
The danger of a substance is defined not by being «light» or «hard» but by a combination of factors: the risk of a fatal overdose, how quickly dependence forms, the effect on the mind and heart, and the unpredictable composition of street drugs. Below is an approximate list of the substances that most often lead to severe consequences.
The 10 most dangerous drugs
The list combines overdose mortality, how fast dependence forms and the harm to the body. It is not a ranking of «strength» but an assessment of the risk to life and health.
A synthetic opioid dozens of times stronger than heroin. A dose the size of a few grains can be fatal — an overdose stops breathing within minutes.
Forms severe dependence quickly. High overdose risk due to unknown purity and mixing with other substances.
A powerful stimulant: insomnia, paranoia, psychosis, exhaustion, cardiac complications. Dependence forms very fast.
Mephedrone, a-PVP and analogues with an unpredictable composition. Cause acute psychosis, aggression, overheating and life-threatening behaviour.
Overloads the heart and vessels: heart attacks, strokes and arrhythmias are possible even in young people. Forms strong psychological dependence.
A long-acting opioid: dangerous overdose and a draining withdrawal that is extremely risky to manage on your own.
Stronger and more unpredictable than cannabis: seizures, psychosis, loss of consciousness, acute cardiac reactions.
Tramadol, codeine, nalbuphine — an underestimated «pharmacy» dependence. They suppress breathing, especially with alcohol or sleeping pills.
Alprazolam (Xanax), diazepam — dangerous because of abrupt withdrawal (seizures) and mixing with opioids or alcohol.
Legal, but by total harm one of the most dangerous: binge drinking, withdrawal, delirium, damage to the liver and heart.
Overdose signs — when to call emergency help
With any of these signs, do not wait: call 103, lay the person on their side and monitor breathing until medics arrive.
The person cannot be woken and does not react to voice or pain.
Slow, irregular or stopped breathing, bluish lips and nails.
Fits, uncontrolled movements, biting the tongue.
Hallucinations, panic, behaviour dangerous to self and others.
What not to do
Do not leave the person alone or lay them on their back — with vomiting this is dangerous.
Do not «sober them up» with alcohol or give other medications «for relief».
At signs of an overdose, do not hope it «will pass on its own».
Do not try to manage withdrawal on your own.
