Bad trips

Weaker than LSD but with more prolonged effects and a higher incidence of bad trips sometimes termed STP (serenity-tranquillity-peace) a synthetic amphetamine derivative, which could alternatively be included in the next grouping. 

Similarly, it is apparent that chlorpromazine does not prevent the LSD sequence of effects and, when given during the LSD experience, may mask perception of some of the changes but not the course of the march of events. Indeed, because of the effects of chlorpromazine per se, most clinicians treating bad trips have learned, if medications are to be used, to employ sedative antianxiety drugs, such as valium. Animal experiments tell us that remarkably small doses of chlorpromazine can be strikingly effective in blocking the effects of LSD on fixed ratio performance (30 Mg/kg), and there was some early hint that less of a 5-HT elevation occurred with chlorpromazine pretreatment in rat brain (22). 

Although some people use ketamine regularly, others may stop using it because off the K-Hole experience—that near-death/out-of-body experience that is seen with higher doses of the drug. K-Hole experiences increase in frequency with repeated use of ketamine, and these frightening bad trips may actually deter people from future ketamine use. 

Bad trips A commonly known outcome of hallucinogenic experience is colloquially known as a bad trip. This essentially consists of a panic episode, sometimes brought on by a dislike of the hallucinogenic effects and fear that the experience will not end. Given that LSD prolongs one s perception of time, it may seem as if the experience will never end and it... 

In all our studies, we were concerned about possible bad trips as well as the more remote likelihood of uncovering a latent psychosis. When testing LSD, we took special pains to ensure a favorable set and setting and selected only volunteers who met the most stringent screening criteria for psychological stability. Nevertheless, some form of hostile behavior surfaced in 20% of subjects given doses above 2.0 mcg/kg (i.e., about 150 meg). Most lower dose LSD tests, however, turned out to be relatively calm and uneventful. 

In addition to these experiments, George Aghajanian proceeded to see if Thorazine would reverse LSD-induced performance impairment. At the time, Thorazine was still the most widely accepted medication for controlling bad trips. George found that it raised NF scores only slightly and did not shorten the overall duration of impairment. Surprisingly, Thorazine sometimes even delayed the final return of performance scores to baseline. 

After Bad Trip to Edgewood aired in the United States, the Canadians wanted to follow it with a small production of their own. Like the British, they also sent a film crew to interview me briefly. Their production echoed the sentiments of Michael Bilton s film. 

I soon had another interesting, rather ironic, encounter. At a 1993 event in Santa Cruz honoring the 50 anniversary of the accidental discovery of the subjective effects of LSD by Albert Hofmann, I met Dr. Alexander Sasha (my intended counterpoise in Bad Trip to Edgewood) in the cafeteria line. As we chatted, it became apparent that we agreed far more than we differed. We hit it off so well, in fact, that he and his wife Ann later invited Judy and me to lunch at their home in Lafayette, California. 

The mechanisms of flashbacks are probably mixed. Some cases may be similar to post-traumatic stress disorder induced by a bad trip (Paton et al., 1973). Abraham (1983) suggested that some of the visual phenomena, such as trailing and after-images, were due to failure of inhibition in visual pathways, possibly mediated in the lateral geniculate nucleus which (in the macaque monkey) contains on-off colour neurons with receptor fields similar to those described in flashbacks. The neurochemical causes of such flashbacks, which can be very disturbing, remains elusive and attempts at treatment are usually ineffective. 

PJ s experiences with drugs were not always good sometimes she had a bad trip , sometimes she did not get stoned at all if the drugs were contaminated with too many adulterants. The expected consequence does not need to occur every time in order for the behaviour to be strengthened. Gambling is the obvious example. Reinforcement that occurs only intermittently may be even more powerful man that which occurs every time. 

Psychedelics alter consciousness in psychopathological directions, but because they are (mostly) reversible, they constitute round-trip tickets to and from forbidden zones in brain-mind space. There are good trips and bad trips. Good trips are characterized by altered perceptions and enhanced mood bad trips by altered perceptions, fear, anxiety, and depressed—or violent—mood. LSD, the psychedelic drug par excellence, can cause both good and bad trips, depending on the individual taking it, the expectations and context of the taker, and the dose and purity of the LSD.
