Caffeine has had a tumultuous relationship with science. For years, it was considered an unhealthy way to start the day, and studies have linked it to anxiety, heart disease and addiction. Today, coffee is portrayed in a more favorable light, but it's not without its flaws. According to a new study, coffee can be harmful to sleep deprived people. At the other end of the drug spectrum, cocaine and LSD are enjoying a renaissance.

DON'T DRINK CAFFEINE IF YOU'RE TIRED.

It may go against your instincts, but apparently it's dangerous to drink caffeine if you're tired. According to a new study from the Walter Reed Army Research Institute, caffeine doesn't give you a mental boost if you're sleep-deprived. Several days of restricted sleep are relatively unpropitious for an effective daily dose of caffeine. Not only will it have no effect, but it may even increase negative side effects such as irritability. This information is especially important for military personnel. Soldiers often fight with limited sleep and may turn to caffeine to increase alertness. However, they may be doing more harm than good. Perhaps they should start fighting the war with cocaine or LSD.

WILL COCAINE REPLACE COFFEE?

Today, cocaine is considered a major cause of extreme violence around the world. However, let's put this negativity aside for the moment and look at its benefits. The leaves of the cocoa plant have been used as an effective stimulant in South America for thousands of years and have a wide range of health benefits. For example, cocaine can be used as a topical anesthetic for surgery due to its rapid numbing effect. It is also an effective vasoconstrictor, making it a good way to treat minor skin lacerations. Internally, cocaine is said to act as an intestinal stimulant that promotes healthy activity in the area. When it comes to mental illness, coke is not very helpful, which brings us to our next drug.

GETTING RID OF ALCOHOLISM WITH LSD

Lysergic acid diethylamide, better known as LSD, is a popular hallucinogen that has been widely used and studied for decades. The government may not consider it a benefit to society, but Norwegian researchers conducted a study in 2012 suggesting that LSD can prevent alcoholics from relapsing while in treatment. Compared to other psychiatric drugs, LSD works in a completely different way. While taking the drug, patients expressed feelings of acceptance toward their alcohol problems in addition to a restored motivation to deal with them. Further studies on LSD and PTSD are currently underway.
