Speaking of Hashish (Hash): Psychoactive effects are the same as those of other cannabis preparations such as marijuana [wikipedia] …
“Once you recognize this, know that a group of scholars of the time, such as … went [to rule] that [such a matter] is forbidden … and the remainder are upon its permissibility. Al-Taqi Al-Majlisi  used to smoke it during [his] non-obligatory Fast, and would abstain from it during his obligatory Fast, wary of what the ‘Awaan would say (now the word ‘Awaan can refer to laypeople, but Shia scholars also use it to refer to Ahl Al-Sunnah).
They based their ruling of impermissibility on two evidences:
The first is what was narrated from the way of Al-Sadiq [‘Alaihi Al-Salam] that he said: If you see people are approaching and inclined towards a matter then abstain from it.
Now, [you would find that] this Hashish (Hash) is being approached by people in a great manner, in such a way that there is no pushing them back … (He then gives how Shah Abbas I – one of the Safavid rulers- tried to stop people from using it, by making it illegal, but they did not stop … so he made it legal and taxed it highly … and that did not stop them either).
The Second is that it is from the wastefulness of money, which was forbidden in the Book and the Sunnah. That is because you might find a person who only has one Dirham, and would [rather] spend it on that and remain hungry. He might also be affected by great harm by getting drunk. We have surely seen, those who have smoked it and became so drunk that he fell in the fire until he burned some of his body parts …”
In the first scan you can also read him saying:
“And some contemporary scholars where of the view that Jum’ah prayers are forbidden, and would harshly [attack] those who do it; rather maybe even he would declare him as a Kaffir.
Then after some time, he became inclined to its obligation, and started performing it. When he was asked about this matter he said: I saw the Imam in my dream, and he ordered me to do it.
He prayed it for a while, and then left it. He might even have said: That the Imam forbade me from it [also] in a dream …”
