Why marijuana can trigger paranoia
New research from the University of Oxford in the U.K. has found that psychological factors can lead to paranoia in people who use marijuana.
For the study, published in the journal Schizophrenia Bulletin, researchers tested the effect of THC, the main active ingredient in marijuana, on 121 participants ages 21 to 50. Two-thirds of the participants were injected with THC at a dose equivalent to a strong joint, while the others were given placebo. The effect of the drug lasted for 90 minutes.
Results showed that among those who were injected with THC, around 50 percent reported paranoid thoughts, compared with 30 percent of people who received placebo. As the compound left the bloodstream, the feelings of paranoia lessened. They also found that THC induced anxiety, worry, negative thoughts about oneself, changed perception and altered the perception of time.
After using a statistical analysis, researchers concluded that these negative feelings and changes in perception may actually cause paranoid feelings in marijuana users. The findings suggest that existing negative feelings may encourage a sense of paranoia when marijuana is used.

Injection stops diabetes in mice
There’s potentially good news for those with diabetes or a high risk of developing it. Researchers at the Salk Institute for Biological Studies say that with a single injection of a specific protein, they were able to restore blood sugar to healthy levels in mice with type 2 diabetes. This treatment also reversed insulin sensitivity and lacked the side effects common in most diabetes drugs currently on the market.
The team injected doses of the protein FGF1 into obese mice with diabetes to assess its potential impact on metabolism. They found that with a single dose, blood sugar levels quickly dropped to normal levels in all the diabetic mice.
The injections seemed to restore the body’s own ability to naturally regulate insulin and blood sugar levels, keeping glucose amounts within a safe range.
Next steps for the research team includes understanding how exactly FGF1 works as well as preparing for human trials.
