The subtle body of a person who is habitually under the influence of marijuana does not necessarily travel to this place, but it will gravitate to a place where it can access the drug in one way or the other, depending on the specific habit and environment used by that deceased person before the body died.

These persons were yogis who were dedicated to using the drug for specific trance absorption states, persons who spent years using the drug and became dedicated to being in the state the drug provided. Most of these persons are like the ones you may meet in India at the Kumbla Mela gathering on somewhere else in India where ascetics or societal rejects live only to get the influence of the plant.

One important consideration is that if the person was habituated to the influence in the physical brain, that person will after being evicted from a material body for good, seek out rebirth so that the subtle body can again get the drug through ingestion in a physical form. But those drug users who managed to transfer their intention to the subtle body, will be more inclined to finding a subtle place where they can remain under the drug's influence.

There is a description in the Srimad Bhagavatam about a dimension (Atala astral place) where users of the drug may find themselves living after death. There they are used by females who use them as stud-horses and who make sure they smoke the drug so as to maintain sexual viriltiy which is required by the women there, who are their captors. (Srimad Bhagavatam 5.24.16).
