Good news for marijuana smokers
Yet a new study has found the opposite: that one of marijuana’s active ingredients actually helps produce new brain cells, while apparently reducing anxiety.
It’s part of a double whammy of good news for pot lovers, as another study has found that marijuana smoke is less carcinogenic than cigarette smoke.
None of this establishes that pot smoking is safe. Some past studies have found it produces notable memory impairments, although there is debate over how long these last.
Nonetheless, the new findings contain “good news for the medical marijuana movement,” chirped a press release from the Journal of Clinical Investigation, which is publishing the study on new brain cells.
[In the experiment new cells grew in the hippocampus, a brain area associated with emotional expression and some aspects of memory formation.]
