Hi There, Thanks for asking. I should say that you have a good observation. That is completely true that discontinuation of taking cannabis when it has been used for a while can bring lack of motivation, change in mood and also sense of loneliness
. She can decrease these symptoms by going to doctor. A natural remedy which can help in this regard is St. John's Wort. Meanwhile, you should know that it has many drug interactions, so if she is taking any medication, it is highly recommended that she asks her doctor about the possible drug interaction. I wish for her a good health.
