Psychedelic-facilitated smoking cessation: An online survey

January 1, 2015 / Addiction, LSD, Mushrooms / Psilocybin, Other substances, Papers, Psychology, Publications, Sociology / By / , ,

Abstract

Aims:
Pilot laboratory results suggest psilocybin may be an efficacious adjunct to smoking cessation treatment. However, no study has examined smoking cessation after psychedelic use in naturalistic settings.
Methods:
We are conducting an online survey collecting demographics, smoking history, and other data from people who self-report quitting/reducing smoking after taking a psychedelic.
Results:
Among current completers (N=164), LSD (49%) and psilocybin (32%) were the drugs most commonly associated with quitting/reducing, with a mode of 2-5 lifetime uses each. Participants reported smoking a mean of 12 cigs/day for a mean of 8 yrs before the experience. 62(38%) reported total and continuing abstinence after their experience, with 29 of the 62 (47%) reporting >1yr abstinence, and 7 (11%) reporting >10 yrs abstinence. Another 67 of the 164 (41%) reported persisting smoking reduction, from a mode of 10-20 cigs/day before, to a mode of <1 cig/month after the experience. The remaining 35 (21%) reported temporary reduction, with 6 of the 35 (17%) reporting >1 yr reduction. Although the majority of withdrawal symptoms were rated as equal in severity to previous quit attempts, depression, irritability, anxiety, and craving were rated as “much less severe.” 141 of the 164 (86%) reported no premeditated intention to quit/reduce smoking, and 159 (97%) described their experience as highly meaningful, with
97 (59%) considering it among the 10 most meaningful experiences of their lives. Participants cited changed life priorities/values (26%), strengthened belief in their ability to quit (26%), and changed future orientation (17%) as the most important effects leading to quitting/reducing. Other changes reported after psychedelic use included reduced alcohol (38%) and other drug use (23%).
Conclusions:
Psychedelics may prompt temporary or prolonged smoking cessation, suggesting that careful administration in a treatment context may enhance motivation in changing addictive behaviors. Psychological and neurobiological mechanisms underlying such behavioral changes require further investigation.

Serotonin 5-HT₂ receptor activation prevents allergic asthma in a mouse model.

Abstract

Asthma is an inflammatory disease of the lung characterized by airways hyper-responsiveness (AHR), inflammation, and mucus hyperproduction. Current mainstream therapies include bronchodilators that relieve bronchoconstriction and inhaled glucocorticoids to reduce inflammation. The small molecule hormone and neurotransmitter serotonin has long been known to be involved in inflammatory processes; however, its precise role in asthma is unknown. We have previously established that activation of serotonin 5-hydroxytryptamine (5-HT)(2A) receptors has potent anti-inflammatory activity in primary cultures of vascular tissues and in the whole animal in vasculature and gut tissues. The 5-HT(2A) receptor agonist, (R)-2,5-dimethoxy-4-iodoamphetamine [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][(R)-DOI] is especially potent. In this work, we have examined the effect of (R)-DOI in an established mouse model of allergic asthma. In the ovalbumin mouse model of allergic inflammation, we demonstrate that inhalation of (R)-DOI prevents the development of many key features of allergic asthma, including AHR, mucus hyperproduction, airways inflammation, and pulmonary eosinophil recruitment. Our results highlight a likely role of the 5-HT2 receptors in allergic airways disease and suggest that 5-HT2 receptor agonists may represent an effective and novel small molecule-based therapy for asthma.

The Philosophy of Psychedelic Transformation

January 1, 2015 / Consciousness, Other substances, Papers, Personal development, Phenomenology, Philosophy / By /

Abstract

Recent scientific research into the therapeutic potential and mechanisms of psychedelic drugs raises intriguing and hitherto largely unexplored philosophical questions. A brief overview of the relevant science is given before addressing these questions. It is argued that psychedelic transformation is a distinctive psycho- pharmacological intervention because its mechanism of action ineliminably involves conscious mental representations, and thus is more transparent to the subject than the mechanisms of other drug therapies. This argument connects with issues in the philosophy of (cognitive) scientific explanation. It is also argued that transformative psychedelic experiences may well confer three distinct kinds of epistemic benefits: knowledge by acquaintance of the subject’s psychological potential, knowledge by acquaintance of the meta-physical nature of the (sense of) self, and revitalized capacities for the acquisition of modal knowledge. Non-naturalistic metaphysical and epistemological claims abound in psychedelic circles; thus, it is important to realize that psychedelics may yield naturalistically acceptable epistemic benefits.
