Smoking marijuana can suppress the body’simmune system , which explains why pot - smoker are more susceptible than non - smokers to certain Cancer the Crab and contagion , according to a raw field of study .

This force ofmarijuanais due to chemicals in the drug that give the axe up the body ’s product of immune system cell called myeloid - educe suppressor cells . While most immune system of rules cell are protective — fighting infection and Crab to keep a mortal healthy — these cell suppress the immune organization , keeping it in handicap , concord to the study .

" Cannabis is one of the most widely useddrugs of abuseworldwide , and it is already consider to suppress immune functions , relieve oneself the user more susceptible to infections and some type of cancer , " Prakash Nagarkatti , a microbiology and pathology prof at the University of South Carolina , said in a financial statement .

Nagarkatti and his confrere focused their written report on cannabinoids , compounds discover in the cannabis plant , to see how they affected immune suppression andtumor growth . Their subject included the annoyance - excuse compound delta-9 THC ( THC ) .

The researchers injected one radical of mice with THC and compared them with a radical not inject with the chemical compound .

The mouse put in with THC had more of the immune - suppressing cell than the mouse who did n’t obtain THC , according to the study .

The researchers get hold that marijuana trigger the production of a monolithic number of myeloid - derived suppresser cellphone — precede to immune inhibition and cancer growth — by activating cells that respond to the cannabinoids find in marijuana , researchers said .

Cancer patients have more of these cells than sizeable people . The suppresser gene cell can evenhinder cancer therapyand promote cancer increment , the study allege .

" Marijuana cannabinoids submit us with a double cutting brand , " Nagarkatti say , because they can get increased susceptibility to malignant neoplastic disease and infections , but they can also afford the threshold to opportunities to treat disorders where a stamp down immune arrangement is good , such as arthritis , multiple induration , lupus and hepatitis .

The study is published in the December return of the European Journal of Immunology .
