Hidden Drug Addiction Can Be Difficult to Identify
Almost 3 million people used drugs in the UK last year. If you compare this with the fact that around 10% of that number sought help for addiction treatment, it shows many people with substance use disorders actively conceal their drug use or do not seek help.
Drug addiction is an ongoing problem in the UK, affecting people from every background. Many loved ones of people suffering want to help but are perhaps unsure of whether the person they know is going through addiction.
There’s no single sign that confirms addiction; instead, patterns of behaviour provide more meaningful evidence.
We’re going to take a closer look at why people hide drug addiction, how to tell if someone is on drugs, and what you can do to help.
Why Are People So Private About Drug Addiction?
Every person engaging in secret drug use has their reasons. However, there are some common motives why a person might hide their drug addiction.
Fear and Stigma
Many people, and society in general, carry a stigma about drug addiction. Users internalise this, carrying around the shame and guilt of their actions, but are unable to stop. They fear judgement from others, so they hide what they are doing to avoid letting anyone down.
Protecting Relationships or Employment
Engaging in a hidden drug addiction can fly in the face of your own values or those of your family and people you know. People keep their drug use hidden because they don’t want to lose the trust of their family, are worried about keeping their job and keeping their finances stable.
Drug addiction may cause people to look at them differently and act, potentially destabilising relationships and their financial situation.
Denial and Addiction
Drug addiction alters brain chemistry and changes behaviours. Rather than face up to the issue, people can minimise the extent of their problem or deny it altogether. Denial protects them from difficult feelings and, in turn, it’s not viewed as a serious issue. If a person does not accept that there is a problem, then perhaps there isn’t one?
7 Signs Someone May Be Hiding a Drug Addiction
There is a range of behavioural signs that point to addiction, with many occurring together.
7 signs someone is using drugs include:
1. Sudden Changes in Behaviour or Personality
People using drugs will likely go through mood swings, especially if they are going through withdrawal, such as stimulants, which can cause irritability.
They will become more secretive with their drug use, and this can lead them to act defensively about minor things. Your loved one may also lose interest in hobbies and relationships as drugs begin to take over.
2. Physical Appearance Begins to Change
You may notice physical changes too. Drugs can lead to weight loss or gain and cause bloodshot eyes, dilated or constricted pupils.
Their personal hygiene may decrease as they lose motivation and focus more on drugs. If abusing opiates or other depressants, they may be tired often. When on stimulants, like cocaine, they may have bursts of excessive energy.
3. Financial Problems or Unexplained Spending
Drugs can take over everything. To fuel addiction, sufferers have to have secretive spending habits, resulting in unexplained debts. This can lead to frequent borrowing from others and may escalate to stealing from loved ones.
Missing money and valuables are common for loved ones of people with addiction.
4. Changes to Daily Routine
People using drugs will often become unreliable. This means that they may disappear for long periods without explanation, have inconsistent work or school attendance and miss key appointments.
Their sleep pattern will also change, sleeping in for longer and staying up later.
5. Increased Secrecy and Lying
Becoming more secretive and lying are at the core of the life of someone suffering from drug addiction. They will become more protective about phones or devices, usually being defensive when questioned.
When asked about where they are, they’ll be vague and will begin to avoid family and these types of conversations altogether to avoid confrontation.
6. Declining Performance at Work, School or Home
Drugs will eventually become the primary focus. This means other aspects of life fall by the wayside. Performance and productivity at school or work will decline, with increasing mistakes and a lack of concentration.
At home, too, there’ll be a decline. Everyday responsibilities will be neglected as more time and effort are put into engaging with their addiction.
7. Changes in Social Circle
Using drugs means interacting with other people with addictions. People with a drug addiction often begin to pull away from long-term friends and begin socialising with people they’re unfamiliar with.
They’ll start to withdraw from family too, isolating themselves and avoiding social occasions where they might be unable to use drugs.
Signs Can Differ Depending on the Drug
Not all drug addictions and people’s relationships with them are the same. Signs of drug addiction vary between substances. Someone who uses stimulants may present differently from someone abusing cannabis or prescription medication.
Though that is the case, behavioural changes often overlap, no matter the substance being abused. The lying, hiding, drug use and social withdrawal are all common signs of the majority of drug addictions.
What To Do If You Think Someone Is Hiding a Drug Addiction
If you want to help a loved one through addiction, talk to them about it. This can be tricky, but there are ways to do it compassionately and effectively.
- You should approach the conversation calmly and in a private place where you won’t be interrupted.
- Avoid judgement. Don’t use the conversation to make accusations or have it during an argument.
- Even though you are there to talk, remember to listen.
- Educate yourself. Learn about drug rehab options and encourage them to seek professional advice.
- In the case of an emergency, do not bother with a conversation. If you suspect an overdose, get immediate medical assistance.
