Long-term cannabis users tend to produce less dopamine, a chemical in the brain linked to motivation. Dopamine levels in a part of the brain called the striatum were lower in people who regularly smoke cannabis, especially those who began taking the drug at a younger age. This explains why some cannabis users appear to lack motivation to work or pursue their normal interests. The lowest dopamine levels were seen in users who met diagnostic criteria for cannabis abuse or dependence, raising the possibility that this measure could provide a marker of addiction severity.

Autism rates have risen over recent years. Heightened awareness and more diligent efforts at diagnosis account for some of the increase, yet researchers believe an epidemic is occurring. One possible factor is the overuse of antibiotics at an early age. This lowers the diversity of the gut microflora and lower diversity of gut microbes is positively correlated with the presence of autistic symptoms. Bacterial richness and diversity are essential for maintaining a robust and adaptable bacterial community capable of fighting off environmental challenges.
