Drug Driving Lawyer Glasgow

What Counts as a Drug Driving Offence in Scotland

Drug driving is prosecuted under road traffic law that sets specified limits for a range of controlled and prescription substances. Unlike drink driving, where the limit is fairly widely understood, drug driving limits are set at levels so low for certain drugs that they can be triggered by lawful use days earlier. That surprises a lot of clients. Someone charged with drug driving after cannabis and cocaine use weeks apart, for instance, may find both substances flagged in a single blood test, even though only one was relevant to how they were driving that day.

The law doesn’t require the prosecution to prove impairment for most specified drugs – only that the substance was present above the prescribed limit. That’s a lower bar than many people expect, and it’s one reason drug driving cases can feel harder to fight than they first appear. A solicitor experienced in this area of road traffic law will look closely at how the sample was taken, stored, and analysed, because procedural failures at any of those stages can undermine the Crown’s case.

Prescription medication brings its own complications. A driver charged with driving without appreciating that a legitimate prescription could still result in prosecution is not unusual, and this is where a defence built around medical evidence and dosage records becomes important.

Police Investigation and What Happens Next

Most drug driving cases begin with a roadside preliminary test, often following a stop for an unrelated matter – a broken light, erratic driving, or simply a routine check. If that test is positive, the driver is arrested and taken to a police station for a blood sample, which is then sent for laboratory analysis. This process can take several weeks, so it’s not uncommon for a driver to hear nothing further for a while before a formal charge arrives by post.

Police Scotland then passes the file to the Crown Office and Procurator Fiscal Service, known as COPFS, who decide whether to prosecute. A citation to attend court, or occasionally an undertaking, follows if the decision is made to proceed. This is the stage at which many drivers first speak to a lawyer, though earlier contact – ideally before the police interview – generally puts the defence in a stronger position.

Court cases involving drug driving are usually heard in the Sheriff Court, and in some parts of Scotland the Justice of the Peace court deals with less serious road traffic matters. Procedure will typically involve an intermediate diet, where the case is reviewed ahead of a trial diet if the matter isn’t resolved earlier.

Penalties, Disqualification and Licence Consequences

A drug driving conviction carries a minimum disqualification period, along with penalty points if disqualification is avoided through special circumstances, plus a fine or, in more serious cases, a custodial sentence. The court also has discretion depending on the level of the substance detected, the driver’s record, and whether there’s any suggestion of impairment beyond the legal limit itself.

Disqualification affects far more than the ability to drive to work. For someone in Glasgow relying on a car for childcare, caring responsibilities, or a job that requires a full licence, having a licence revoked can threaten their livelihood. This is where exceptional hardship arguments sometimes come into play – though the threshold is genuinely high, and courts in Scotland don’t accept these arguments lightly. Special reasons arguments are a separate route, used where the circumstances of the offence itself, rather than its consequences, justify departing from the usual penalty.

It should be said plainly: no lawyer can promise a particular outcome, and anyone who does should be treated with caution. What a solicitor can do is investigate and prepare your case properly, identify weaknesses in the Crown’s evidence, and present mitigation that gives the court a full and accurate picture.

Building a Defence Case

Every drug driving charge deserves scrutiny rather than assumption. The defence case might turn on the calibration of testing equipment, the chain of custody for the blood sample, or whether the arresting officer followed correct procedure at the roadside. In some instances, expert toxicology evidence is needed to challenge the Crown’s interpretation of test results, particularly where prescription medication or a delay between driving and testing is involved.

Solicitors who regularly appear in Scottish courts on road traffic matters understand how COPFS approaches these prosecutions and where cases are most likely to be won or lost. That familiarity with local court practice – how a particular Sheriff Court lists its diets, what evidence a Fiscal will typically rely on – makes a genuine difference to how a case is prepared.
