It’s a known fact that smoking adversely affects the body, particularly the lungs.
Scientists are finding that, just as with secondhand smoke from tobacco, inhaling secondhand smoke from marijuana can make it harder for arteries to expand to allow a healthy flow of blood.
Researchers have discovered that the lungs play a far more complex role in mammalian bodies than we thought, with new evidence revealing that they don't just facilitate respiration - they also play a key role in blood production.
In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals' circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components.
