The study suggests MDPV may be more addictive than methamphetamine, with rats working harder to obtain the drug.
A study found that insufficient sleep raises levels of a substance in the body that controls pleasurable eating, leading to increased hunger and appetite. The research suggests that this may be due to an elevation in the endocannabinoid molecule 2-arachidonoylglycerol, which is involved in signaling rewarding events and enjoyment of food.
Designer stimulants, packaged as 'bath salts' or household products, have become a growing concern in the US, with reports of agitation, fast heart rates, and violent behavior. Research suggests that these substances can be deadly, with no formal guidelines for medical treatment of acute toxicity.
