L

LSD (Acid)

LSD, short for lysergic acid diethylamide and commonly known as Acid, is a synthetic hallucinogen. Hallucinogens are substances that induce hallucinations, or false sights, sounds, smells, tastes, or physical feelings that may seem real but aren’t. LSD is known for its relatively harmless psychoactive effects; deaths following use of LSD are very rare, and often occur due to other medical complications.

Some hallucinogens are natural and legal, but LSD is not. This is most likely due to its extremely high potency; even moderate doses of LSD can produce mind-bending, reality-warping effects called “trips”. These trips can be pleasurable or calming, but can often turn unpleasant and scary. Given that there is no way of cutting a trip short, these bad trips can be extremely undesirable and even have lasting psychological effects.

M

Major Depressive Disorder

Depression, also known as major depressive disorder or clinical depression, is a common mood disorder characterized by persistent feelings of sadness and low mood, which can result in thoughts of self-harm or suicide when untreated. These feelings are not caused by grieving upsetting events in one’s life, but rather a result of changes in brain chemistry. Depression is one of the most common mental disorders in the U.S., with around 7% of adults and 4.4% of children having some form of depression.

Depression can cause more than just sadness; it can affect thought patterns, interpersonal relationships, and interest in daily activities. The disorder also negatively affects the ability to perform daily tasks, like getting out of bed, brushing teeth, sleeping, eating, etc. Given the wide variety of symptoms, depression is quite treatable. Treatment may include talk therapy and medication, or even guided lifestyle changes, which can mitigate the symptoms of the disorder while not necessarily treating it.

Marijuana (Weed)

Marijuana, also known as weed or pot, is a drug composed of the dried leaves, flowers, stems, and seeds from plants of the Cannabis genus. Among the common Cannabis plants included are C. sativa, C. indica, and C. ruderalis. Cannabis and marijuana are often used interchangeably, but marijuana is technically different as it only consists of cannabis products that contain THC, the main component that gives marijuana its psychoactive effects. These effects include relaxation, mild euphoria, and an altered sense of time.

Throughout the 20th century, the legal status of marijuana in the U.S. was ruminated on, adjusted, restricted, and relaxed until the 1990s, when decriminalization efforts began and medical uses of the drug was legalized in multiple states. Now, many states have legalized both medical and recreational applications of marijuana for people over the state-designated legal consumption age.

MDMA ( Molly / Ecstacy )

MDMA, short for 3,4-methylenedioxy-methamphetamine and also known as Molly or Ecstacy, is a synthetic drug that has the effects of both a stimulant and a psychedelic. It induces excitement, high energy, and euphoria while distorting one’s perception of time. MDMA is classified as a Schedule I drug, meaning that it has no practical applications outside of recreation and it has potential to be abused.

Possible negative effects include nausea, involuntary jaw clenching, and high blood pressure. The high induced by MDMA can also increase anxiety and cause extended bouts of depressive thoughts in the aftermath of drug use. MDMA overuse very rarely results in death, but there are cases of repeated use causing heart conditions that can lead to fatal complications. Due to its reputation as a club drug, MDMA is often accidentally overused in nightclubs and social gatherings.
