How do you perceive the current cultural and societal attitudes in America towards psychedelic mushrooms?

I think that there is an increasing awareness of the potential for psilocybin to be a useful therapeutic.  Because of the attention being brought to the research examining its uses there is also a common misperception of its legality.  Although psilocybin has been "decriminalized" in several municipalities and even the State of Colorado, it remains on the federal controlled substances list and is therefore an illegal substance in the eyes of the law of the country. 

Can you elaborate on the potential influence of media representation and public discourse on shaping American attitudes towards psychedelic mushrooms?

In my opinion, the media representation of the often somewhat sensationalized research results is leading to a focus on the substance rather than on the reality that far more important that the intoxicating effects, is the transformative ability of psilocybin to make therapy more effective.

In your opinion, how might the prevailing attitudes towards psychedelic mushrooms impact mental health discourse and treatment options in the United States?

While attitudes are adjusting, in my opinion, it is extremely unlikely that psilocybin will become legalized as a medication in the near future.  Because mushrooms are a natural substance, there is not the opportunity for big pharma to make the kind of money needed to recoup the costs of doing the clinical trial work to get FDA approval.  That said, I am very hopeful that the interest in psychedelic mushrooms may help us shift treatment options from merely reducing symptoms to actually addressing the root cause of mental health challenges.  In order for people to be mentally healthier, they have to heal their wounds and shift their thinking.  They have to change their minds!

From a psychological perspective, how might personal experiences with psychedelic mushrooms contribute to shaping one's attitudes and beliefs about their societal implications?

I think that a personal experience that is positive might make one have a good attitude about changing the laws regarding legalizing the use of psychedelics as medications.

Are there any legal or regulatory implications associated with the changing attitudes towards psychedelic mushrooms, and how might this influence policy making?

The reality is that psychedelic mushrooms are illegal to possess, sell, or use.  Even though attitudes toward them are adjusting and they are not necessarily being regarded by the public as "bad drugs", until policies are developed that can take into consideration controlled use of them as medications, their status as illegal means that legitimate medical professionals cannot recommend them or supervise the use of psychedelic mushrooms without risking sanctions or loss of their  medical license.
