2 March 2011 - Jessie J has boasted off her clean lifestyle, but there was an incident where she ate a "whole hash cake" in Amsterdam without realising it had cannabis in it.
The 'Do It Like A Dude' singer was on tour with Chris Brown at the time and ate the cake and had to go to hospital after she reacted badly.
In an interview with Style magazine, the 22-year-old said: "I accidentally ate a whole hash cake in Amsterdam while I was on tour with Chris Brown. I had to call an ambulance because I started convulsing."
Jessie J, who suffers from an irregular heartbeat, added: "I called my mum and she was like, 'I'm glad you did it because you'll never do it again'."
Friends Of Cannabis found some information on Coffeeshopsamsterdam.com about consuming cannabis and enjoying Amsterdam while preventing possible negative experiences. Here are some tips:
* THC, one of the active ingredients in cannabis, is a mood enhancer. Make sure you are having a good day that you wish to make more intense or refrain from using cannabis products. Drug use is a personal choice and should not be influenced by another person’s opinion.
* Use caution when combining cannabis and alcohol. Smoking a joint can make your drinks feel many times stronger!
* Allow 20 minutes to two hours for a space product to start working, and if the cake is larger try eating half and wait at least an hour before consuming more cannabis.
* Smoking joints, eating space cake or using a vaporizer will lower the amount of sugar in your blood. This can sometimes lead to nausea, ringing ears, and sweating. If this occurs just drink some sugar water or juice, or eat something sweet (avoid caffeine). Fresh air usually helps and so does a good meal, but panicking will not!
