Hi and welcome to Healthcare Magic. Thanks for your question... Many substances of abuse, like alcohol, marijuana coccaine, etc. are associated with different psychiatric problems. You have not mentioned if you are still continuing to take marijuana or if you have started again recently after quitting. If so, then it is likely that your current psychiatric problems are related to it. If, on the other hand, you have developed the current depressive symptoms while you have been clean since the last episode, then you may be having a recurrent depressive disorder. It is also important to understand if your personal and social circumstances are causing you stress, since stress can be a precipitating or perpetuating factor for depression. It is a good thing that you are aware of your problems and are seeking appropriate help for the same. I hope that you have been started on Paxil only on advise of a doctor. It is now important that you continue medication regularly and have periodic reviews to monitor your progress. Also, as anti-depressant medication usually take a few weeks to bring about their full effect, you have to be patient and continue them regularly without stopping them pre-maturely. Since you seem to be having recurrent symptoms, your doctor may advise to continue medication for a longer duration this time. Psychological therapy can definitely improve the outcome in depressive disorders and often, a combination of medication and therapy yields best results. So, do go for regular therapy sessions as advised and stay completely off marijuana or any other substance of abuse. All the best. - Dr. Jonas Sundarakumar Consultant Psychiatrist
