At first, drugs can seem like a bit of harmless fun or even help you through a difficult patch in your life. But drug abuse can quickly spiral, and before you have time to realise what’s going on, you are caught up in addiction. Drug addiction doesn’t always look like you might expect so the early warning signs are often brushed aside. That is why it’s so important to understand how drug addiction takes hold, what fuels it and how the right support at the right time can change everything.
What is drug addiction?
Drug addiction is a chronic, medically recognised condition where you lose all control over your drug use. A startling number of people in the UK are regular drug users with substances like cannabis, cocaine, ecstasy and methamphetamine all common on British streets and in British homes.
There is often a kind of “honeymoon period” where drug abuse feels manageable, and you are able to control when, where and how much you are taking. Eventually, however, drug addiction takes hold and you can’t stop or even cut down, even as you watch your health suffer and your life unravel.
- Between April 2023 and March 2024, a total of 310,863 adults were in contact with drug and alcohol treatment services in the UK, a 7% increase from the previous year (290,635).
- In 2023, there were 5,448 drug poisoning deaths registered in England and Wales.
- In 2023/24, there were 145,558 hospital admissions in England with a primary diagnosis related to drug misuse.
- A substantial number of individuals entering drug treatment programmes reported concurrent mental health and addiction needs.
- For the year ending March 2024, approximately 8.7% of adults aged 16 to 59 had used an illegal drug in the previous year.

How does drug addiction develop?
The path into drug addiction often begins so slowly and imperceptibly that it can obscure the early signs and stages, making it easy to underestimate the seriousness of the situation.
Drug addiction often begins as recreational use, experimenting with your friends or taking the edge off after a bad day at work. At this stage, drug abuse seems harmless and completely manageable. However, what starts as sporadic can quickly become a regular part of your routine. You might find yourself using drugs every evening to relax or your weekend drug sessions escalating.
The more regularly you use drugs, the more your body gets used to them and soon, small amounts don’t do it anymore. This is what we call building tolerance. Once tolerance kicks in, it doesn’t take long for dependency to develop, which means drugs become more of a need than a want.
Stopping can then bring on tough withdrawal symptoms, things like feeling on edge, hurting physically or riding a rollercoaster of emotions. When it reaches this level, drugs become an emotional crutch, start to dominate your life, steer your choices and cause serious damage.
Drug addiction signs to look out for
The shift from occasional drug use to addiction can be subtle and easy to miss, especially if you’re managing to keep it hidden. However, recognising these symptoms of drug addiction can help you identify when it’s time to seek help:
- You’re constantly waiting for the next chance to use it.
- You’re keeping secrets or lying about your drug use.
- Drugs have become your go-to solution for dealing with stress and bad days.
- Withdrawal symptoms like restlessness, irritability or physical discomfort appear if you go too long without drugs.
- The amount of drugs you need to feel the same effects has grown.
- Drug use is negatively affecting your professional life and personal relationships.
- Attempts to reduce or stop your drug use have repeatedly failed.
- You persist in your drug use despite obvious adverse consequences.
If these signs resonate with you, don’t lose hope. Professional drug detox and rehab treatment can help you break out of the cycle.
