Effects Most inhalants are depressants. Their effects are quite similar to those of alcohol or cannabis. Small amounts can have a very rapid effect. Inhalants reduce the user's inhibitions and can cause laughter and mild excitement or even euphoria. They can also cause anxiety.
Some users engage in reckless or dangerous behaviour while under the influence of inhalants.
The effects of inhalants usually last about an hour. The initial excitement often gives way to drowsiness. Hangovers or headaches often occur after the initial effects wear off. Large doses of inhalants can lead to disorientation and loss of coordination as well as nausea and diarrhoea. Habitual use can cause flu-like symptoms such as sneezing, coughing and a runny nose.
