There has been very little scientific research on the effects of ‘recreational’ or ‘party drugs’ on blood glucose. Stimulants can increase your level of physical activity, which can lower blood glucose levels. Some drugs can cause similar sensations to the early warning signs of a hypo, while others may mask the symptoms of a hypo. Some drugs also have ‘come-downs’ which can impact your motivation to look after your type 1 in the following days.
The best idea is to avoid recreational drugs altogether, but if you can’t avoid them you should talk to your doctor or healthcare team about strategies to reduce your risk of injury, like checking your blood glucose levels regularly and being around people who understand what to do if you have a hypo.
