The Fife Alcohol and Drugs Partnership say that they have been alerted to an increase in harm caused by synthetic cannabis – sometimes known as ‘spice’ – which is intended to have the same effects on users as the Class B drug.

Although marketed as legal, the Partnership said that there had been “deaths reported within Europe” and “recent incidences in the UK where people have had to be hospitalised” due to its use.

Dr Michael Armanyous, consultant psychiatrist with NHS Fife’s addiction services, said symptoms “should not be ignored”, commenting, “Although synthetic cannabis is marketed as legal, people have to be aware that this does not mean that it is safe.

"So-called legal highs do not come with any quality control, so users are unaware of what is really being provided.

“People have recently been reporting feeling dizzy, persistent vomiting, chest pains, palpitations, and convulsions after taking synthetic cannabis. These symptoms can be life threatening and should not be ignored.

“If you suspect someone may be having a bad reaction or overdose due to the substances they have taken, the simple advice is to seek emergency help by calling 999 and asking for an ambulance.” Ian Sloan, chair of the Fife Alcohol and Drugs Partnership’s working group on new psychoactive substances, added, “This health warning highlights the dangers of so-called legal highs.

"Fife Council and its partners will continue to do everything in its power to stop the supply of these harmful drugs, and I would reinforce the advice of health professionals to seek urgent medical help if you or someone you know becomes unwell after taking any of these substances.” A helpline for those concerned about drug use is available seven days a week by calling 0800 587 587 9, and anyone with information about the supply of illegal substances can contact Police Scotland on 101 or Crimestoppers on 0800 555 111.
