Newbie Question. Are we allowed to mention.....

Hi.
We are very happy to have found this and have just joined, and posted our introduction on the forum.
However, the comedy videos we produce on YouTube are based on the following
Cannabis
Politics
Mental Health
All three of which we have first hand experience of, for many years collectively.

When chatting on here, can we mention the above in a respectful and contextual manner, especially cannabis?
Thanks.
