Health - Can Cannabis Cause Abdominal Pain.

[Tasty]

well ill just get straight to the point, SWIM has been suffering sever abdominal pain for the past 2 months and doctors cannot find the cause ( and are less willing since SWIM told them of cannabis use )

2 days ago SWIM's abdominal pain reached the highest level yet and caused severe vomiting for around 4 hours causing SWIM to start vomiting blood and was rushed to hospital. The doctor was not very helpful as they blamed everything on cannabis but did mention that it can cause abdominal pain. SWIM has never heard this before and is wondering if this is a possibility.

SWIM background: used cannabis for around 3 years constantly and in the past year has drastically lowered the amount smoked since SWIM was no longer enjoying smoking a lot. SWIM is not addicted as they use cannabis purely for relaxation at night when watching movies and has stopped smoking cannabis since being told about it being a possibility for the pain.

Type Smoked: SWIM has been smoking mostly soapbar hash ( pretty low quality hashish typical in scotland ) but smokes buds whenever possible.
SWIM has never experienced bad effects from green but used to have headaches when smoking too much hashish.

SWIM doesnt mind if he has to stop smoking if it is the cause of the pain, but would like to know from more experienced swimmers if it could be the cause of the pain as SWIM does not want to have to undergo surgery.

thanks in advance
