Could Decriminalizing Drugs for Personal Use Actually Increase Addiction Rates? What Ireland’s Debate Reveals

Dublin, Ireland, MMN Correspondent: On June 24, 2026, Aontú leader Peadar Tóibín stepped into a national conversation that has been simmering for months. An Oireachtas committee had just recommended decriminalizing the possession of all drugs for personal use. Tóibín’s response was direct and measured. He argued that such a policy shift might not just fail to solve the problem but could create new ones. What exactly happens when a society removes legal consequences for possessing substances like heroin and cocaine? That question is now at the center of Ireland’s drug policy debate.

Tóibín pointed out something that many people might not have considered. The proposal includes highly addictive drugs like heroin and cocaine. These are not substances typically associated with minor infractions. He noted that the public might be surprised to learn that possessing these drugs would be treated similarly to a traffic violation. The concern here is about the message such a policy sends. When the state removes criminal penalties, it can signal that the behavior is no longer considered dangerous or unacceptable. This shift in perception could weaken the deterrent effect that current laws provide.

Consider the numbers. Only about 10% of the population regularly uses drugs. That figure is significantly lower than alcohol consumption rates. Tóibín highlighted that the illegality of drugs gives parents and educators a clear tool to discourage experimentation. It is easier to tell a child not to do something when it is against the law. Remove that legal barrier, and the state may appear to be giving tacit approval. This could lower the perceived risk among young people, potentially leading to higher initiation rates. The question becomes whether a policy designed to reduce harm might inadvertently increase use.

International examples offer some insights. Portugal decriminalized all drugs in 2000. Initially, treatment access improved. But over time, therapy uptake stabilized or even declined in some areas. Public drug use became more visible in certain urban neighborhoods. Open air drug markets emerged in places that had not seen them before. Canada took a more lenient approach to cannabis and expanded harm reduction services. While some users accessed support, overall cannabis use among youth increased. Public consumption became more common. These outcomes suggest that decriminalization alone does not automatically lead to better health outcomes.

Mental health is another critical factor. Scientific studies consistently link regular cannabis use to higher risks of psychosis, schizophrenia, and depression. This is especially true for adolescents whose brains are still developing. Research published in The Lancet Psychiatry found that daily cannabis use during teenage years can increase the likelihood of psychotic disorders by up to 50%. These findings reinforce the idea that even substances often considered mild carry serious consequences. Tóibín raised a valid point about the government’s dual stance. On one hand, it promotes bans on cigarettes due to their links to lung cancer. On the other hand, it considers decriminalizing hashish, which is also known to cause respiratory issues and cognitive impairment. This inconsistency can confuse citizens about what constitutes a safe lifestyle choice.

Proponents of decriminalization often argue for a health focused model that emphasizes rehabilitation, education, and support services. They believe this can coexist with punitive measures. Tóibín challenged this notion by pointing out that in practice, decriminalization often leads to reduced enforcement pressure. This can weaken the justice system’s ability to target large scale trafficking and organized crime. Supply chains remain under criminal control. Violence and exploitation persist, sometimes escalating due to competition for market dominance. The question is whether removing penalties for users actually disrupts the illegal drug trade or simply shifts the burden elsewhere.

Another important consideration is that decriminalization does not address the root causes of addiction. Without robust investment in mental health care, trauma counseling, and community based prevention programs, simply removing penalties may do little to reduce dependency. Vulnerable populations could be left without adequate support. The absence of a comprehensive strategy risks creating a situation where people are no longer punished for drug use but still lack the resources to overcome addiction.

Tóibín also highlighted a paradox in the proposed policy. Decriminalization applies only to personal possession, not to supply or distribution. This means users face no legal consequences, but dealers and traffickers remain subject to harsh penalties. Such a split in enforcement could drive underground markets deeper into secrecy. It might fuel corruption and violence while failing to curb availability. The question becomes whether this approach actually makes communities safer or simply changes the dynamics of the illegal market.

Ultimately, any effective drugs policy must prioritize three goals: reducing the number of users, preventing lives destroyed by addiction, and protecting mental health. Decriminalization could lead to increased drug use, higher rates of harm, and more overdose deaths. These outcomes would contradict the very purpose of public health reform. As nations around the world explore different approaches, Ireland stands at a crossroads. The debate reflects broader tensions between compassion and deterrence, public health and law enforcement, individual freedom and collective safety. While the call for reform stems from genuine concern about over policing and human rights, evidence from other countries suggests that decriminalization alone is insufficient. It may even exacerbate the problems it seeks to solve. The path forward demands not just policy change but a holistic, evidence based strategy that addresses both the symptoms and causes of substance misuse. Without it, the promise of safer communities may remain just out of reach.
