How can I recognise the signs of drug taking?

It is often difficult to tell if someone is using drugs because different substances can affect people in different ways. However, the following signs apply in a great many cases:

• Sudden changes in mood and behaviour e.g. from happy and energetic to moody and irritable
• Abnormal sleep patterns
• Loss of appetite
• Depression
• Lack of motivation
• Lying and stealing money or goods
• Secrecy about activities and whereabouts
• Keeping late hours and new or unknown friends
• Small plastic or elaborately folded (wraps) packaging
• Burnt foil and spoons, syringes and small bottles
• Shredded cigarettes
• Strong sweet smoky smell
