Drug addiction is often defined as not being able to stop using even though the harm is clear. This can be so frustrating because you really want to quit, but it’s just not working. Many people promise themselves a fresh start and mean every word, but find their determination isn’t enough to resist cravings, withdrawal symptoms, or addiction triggers. That doesn’t happen because you’re weak or because you’re lying to yourself about really wanting to quit. Drug use changes the brain, notably many of the systems you need to stop, like the ones connected to self-control and judgement. Understanding this isn’t a magic cure for addiction, but it can stop you from blaming yourself and help you find the support needed.
How drugs change the brain
The brain changes when drug use continues for a long time. Your brain’s reward system becomes less sensitive, so ordinary pleasures stop feeling rewarding, and the drug slowly becomes the only way to feel good. Your stress systems and learned habits also get stronger, so cravings grow more powerful and hit more often. The brain regions responsible for self-control and resisting impulses grow weaker too. All of that together can cause increased drug use, even if you know it’s dangerous or you’re trying not to use more.
Tolerance, dependence and withdrawal
With regular drug use, you grow more tolerant to the effects, and the amount that used to work stops working. It can then be easy to start taking a little more every time, and if this continues, you can become drug dependent. This means your brain and body now need the drug to feel level, and stopping brings on withdrawal.
Drug withdrawal symptoms vary from one substance to another. Some versions are mostly miserable, but others can cause very dangerous symptoms like seizures, extremely high heart rate and blood pressure, severe depression and suicidal thoughts. Even milder drug withdrawals can be uncomfortable enough that they cause a relapse.
So if you’re using a lot every day, please don’t stop everything suddenly on your own. Speak to a doctor or a professional drug detox service like Bayberry so you can plan and detox safely.
Why drug use stops being a choice
The first time you take a drug, it usually is a choice, even if that’s a choice made from a place where you’re desperate, or you don’t understand the dangers. But at some point, you stop deciding to use and start doing it compulsively.
Addiction is skilled at making it feel like you’re still choosing to use drugs, but a person making a free choice doesn’t fight themselves or know deep down they shouldn’t be doing this. When you use drugs even though you promised yourself you wouldn’t, and you hate it while it’s happening, that is a huge sign of addiction.
As explained above, part of the problem is that the brain systems linked to willpower are weakened by repeated drug use. While it can be easy to blame yourself, the addicted brain is just not capable of resisting the pull anymore.
Where cravings come from
Cravings come from the drug itself, but also from the people, places, times, and feelings that your brain associates with using. That means payday, a particular street, a row with your partner, or even a good mood on a sunny day can all set off a craving. These things are often called triggers, and they continue firing a long, long time after you stop using drugs.
You can’t switch your triggers off just by knowing what they are, but you can plan around them once you do. At Bayberry, we teach our clients how to do just that, with trigger identification and management a major part of relapse prevention.
Using to cope, and the loop it creates
Some people use drugs to cope with anxiety, loneliness, depression, or traumatic experiences. Many drugs really can help you escape for a little while, especially at the start.
But the consequences of drug addiction are painful things that need coping with too. So the thing causing the distress ends up being the thing that relieves it, and the cycle repeats. From the outside, using again looks senseless, but from inside the loop, it can seem like the only solution.
Trying to stop on your own
None of this means you can’t stop, and lots of people eventually do. But it explains why just determination is often not enough. Drug addiction behaves like other long-term medical conditions, and around half of the people treated for addiction use again at some stage. This really isn’t that unusual in terms of illness, and people with conditions like asthma, hypertension, and diabetes have very similar relapse rates.
Understanding that relapse is often just a part of recovery can show you that if you’ve stopped and started again before, that history doesn’t rule you out. Even people who have relapsed multiple times before can and do go on to make a full recovery. Most long-term medical conditions get treated in rounds, with the plan adjusted each time based on what’s been learned, and the same approach works for addiction.
Preparing to succeed
As the old expression goes, a problem shared is a problem halved, and the first step for quitting drugs successfully is to tell someone about it. That could be your GP, or an addiction treatment service like Bayberry. The NHS does provide outpatient recovery services for various drugs, but there is limited availability. Bayberry has residential drug rehab centres across the country, with admission possible in just a couple of days.
You may not be able to quit drugs safely while waiting to start treatment, but you can still prepare. Let people you trust know what’s going on, research all your options, ask loved ones to help out while you’re in treatment, and listen to your doctors or rehab admission team. When it comes time for treatment, be open and honest, and know that just reaching out is a huge step.
How drug addiction treatment can help
Treatment at Bayberry doesn’t rely on your willpower. We carry out a full medical assessment when you arrive to understand what you’re taking and why. A medical drug detox gets you through withdrawal safely where stopping alone would be dangerous, and therapy deals with the reasons you were using. Because addiction is a lasting condition, our support carries on through aftercare, with ongoing group therapy once ordinary life starts again.
All of this works on the determination you already have to make a change. That is key to recovery, and the more you put into drug rehab, the more you’ll get out of it. If you do experience a setback after treatment, we simply use that as information to adjust and improve your recovery plan.
