one of the first scientists to take an interest in psychedelics was dr timothy leary.logist at harvard university in the us in the 1960s. he would give people mushrooms to see if it could change their behaviour as a kind of therapy. unfortunately, his research project got rather out of control and he tore up the scientific rule book and he stopped doing quantitative research — research with numbers, scientific research. and hejust started giving psilocybin to his students and to anyone he met. and his research experiments, rather, turned into psychedelic parties. harvard got wind of it and they closed the project down pretty quickly. because of this bad publicity, serious research stopped. and that's why little is scientifically known about psychedelics compared with other drugs. something which dr carhart harris wants to change. there was some sort of irresponsible messaging going on and a wave of increased recreational use. the whole "turn on, tune in, drop out" message that people were coming up with, timothy leary. but what we have today is a much more mature, i th

however, you have timothy leary, an individual, a professor who is highly educated, who figures he can do research to get his .ay out of this legal bind theso, what he discovers is marijuana tax act is unconstitutional. as i mentioned earlier, if you wanted to be in possession of , you have to get the tax stamp. the only way to get the tax stamp is you would have to present the marijuana. that is an issue because it violates the fifth amendment of because the touche and p can give me a tax stamp -- all the constitution. you can't give me a tax stamp and i can be in possession of marijuana if i have not gotten stamp yet. whoas causing individuals wanted access to marijuana self-incrimination, right? he is able to convince these supreme court in a decision, leary versus the united states in 1969 . they decided in may 2 team it unconstitutional for the fifthion of the amendment. the u.s. does not rest on this. we have the court decision that basically declares the tax act unconstitutional. aside from a range of drug culture that should allow for ,trong control of the substance we see that

however, here you have timothy leary, an individual, a professor who is highly educated, who figures he can do some research to get his way out of this legal bind he is in. so what he discovers is, and through the work of his legal team, that the marijuana tax act is actually unconstitutional. because, as i mentioned earlier, if you wanted to be in possession of marijuana, you have to get a tax stamp. the only way for the government to give you that tax stamp is you have to present the marijuana that you're trying to get the tax stamp for. that is an issue because it violates the fifth amendment of the consultation around self-incrimination. you cannot give me a tax stamp if i do not have the marijuana that i am trying to pay the tax for, and i cannot be in possession of marijuana if i have not gotten the tax stamp yet. it was causing an individual who wanted access to marijuana to face self-incrimination. so he is able to convince the supreme court in this decision the united states in 1969 that decided, in may, to deem it unconstitutional for the violation of the fifth amendment. t
