A new study indicates that marijuana damages the immune system and makes the body vulnerable to diseases such as cancer and pneumonia. The study was published in the European Journal of Immunology.

It was discovered that THC–the main psychoactive ingredient present in marijuana increases the production of a flood of cells that weaken the body’s inbuilt defences.

The study points that marijuana increases the body’s vulnerability to breast, bladder, lung and other tumours, as well as bacterial infections such as legionnaires disease.

High-strength cannabis strains such as “skunk” may be extra-damaging due to extra-high THC content.

Marijuana provides positive results in treating several devastating mental health problems, however its potential to damage the immune system has received less attention.

In tests on mice, researchers triggered the production of a ‘massive’ number of immune cells called myeloid-derived suppressor cells or MDSCs.

These normally act as a safety brake on the immune system, stopping its battle against disease from spiralling out of control. But in the case of cancer, they may actually make it easier for tumours to grow.

‘These results raise interesting questions on whether increased susceptibility to certain types of cancers or infections caused from smoking marijuana (cannabis) results from induction of MDSCs,’ said Prakash Nagarkatti, lead researcher from the University of South Carolina.
