I was wondering about the possible intensifying nature of such things. Due to not enough data, it seems to depend. One would have to be sure of any party in question's type, for one, but more acuity of dominant functions might be apparent. In some instances and other accounts, more preference for inferior functions can be noticeable via some shifts in mood.
I would think a certain amount of arbitrariness would be needed to be aware of. But it would be interesting to see different effects for different people... I would wonder how a Ne-Fi would respond to something.. Would the influence be apparent via some erratic behavior or would they seem kind of different due to a less frequently seen mode of behavior?
While it's true pot can provided increased sensation, that isn't the only thing it does. They call it stoned because what can be described as Ti-Si loops seem more intense. Half the time it's even difficult to move, yet people of varying type seem to have different responses.. Some would have no problem being active and others seem to immediately want to engage in their dom aux or tert Se (aux Ni). Sentiments can be expressed in alternate ways. Some people even report other people turning into assholes when they're stoned. There are too many opinions. Fi variances could even convince the vessel they want to engage in something they may or may not have had the compelling desire to be motivated to act towards otherwise.
A lot of things would have to be ascertained before saying anything definitive.
