That great, geologically young mountain arc is about 1, miles 2, km long, stretching from the peak of Nanga Parbat… For thousands of years the Himalayas have held a profound significance for the peoples of South Asia, as their literature, mythologies, and religions reflect.

A young man shows the LSD tabs on his tongue. This is in part because there have never been scientific research studies on how LSD affects the brain. It's believed that LSD works similarly to serotonin, a neurotransmitter responsible for regulating moods, appetite, muscle control, sexuality, sleep and sensory perception.
LSD seems to alter the way the brain's serotonin's receptors work. It may inhibit neurotransmission, stimulate it, or both.
It also affects the way that the retinas process information and conduct that information to the brain. As little as 0. In the s, users commonly ingested four times as much.
A small amount is left in the body by the end of the trip and is probably gone entirely a few weeks afterward. A common urban legend maintains that LSD stays in the body forever, in minuscule amounts in the brain or spinal fluid.
People who believe this say that the brain stores and releases molecules of LSD over time, and this is what causes flashbacks. A flashback occurs when a person who has used LSD in the past has an experience, lasting anywhere from seconds to hours, similar to that of an actual trip.
Some LSD users enjoy them and consider them "free trips," while others find them incredibly unsettling. Most users don't experience flashbacks, and some people claim that they don't really exist, making the subject a controversial one.
A study found no link between using psychedelics and experiencing flashbacks. Nevertheless, some psychiatrists say some of their patients report this experience [source: Among people who have reported experiencing flashbacks, many are also mentally ill.
Some doctors suggest that what the user perceives as a flashback is really a form of psychosis or mental illness that may have emerged due to LSD use.

It is worth noting that many studies in this area take social media use as the starting point or “independent variable,” and therefore cannot rule out that some “deeper” cause — political interest, for example — is the reason people might engage in SNS use in the first place.
Further, some researchers see SNS use as a form of participation and engagement in and of itself, helping. A single-dose user should be able to clear the drug efficiently from his/her system in under 2 days.
On the other hand, frequent/long-term users could take longer than 2 days to fully eliminate hydrocodone; resulting in a positive urinalysis (e.g. failed drug test) for much longer than 2 days.
