Illegal drugs are becoming easier to access for children in the Highlands, police have warned.

There has been a significant increase in reports of drug-related activity in the region, according a letter issued to parents by Police Scotland and Highland Council.

In the letter, they said the risks associated with drug use "seem to be more prevalent than in the past".

They also warned a greater number of children are becoming involved in drugs at a younger age.

It said: "Pupils, parents and carers need to be aware that young people of all ages have been identified as both using and supplying harmful substances in all areas and seem to believe that such activity is 'normal' for them and others.

"Controlled substances previously believed to not have been a significant issue for young people in many areas in Highland are now readily available and it is possible for anyone - especially young people - to access a wide variety of substances in any area of Inverness."

Heroin, cannabis, crack cocaine, MDMA and cannabis were all cited as examples, along with new psychoactive substances often referred to as "legal highs".
