There's a distinction on who will carry your burdens. When you are in the light, that is with Jesus, he carries your burdens. As you walk closer with Jesus, he will always carry your burdens.
When you use medicinal marijuana, inevitably the enemy comes into action. He will behave in manners that make your burdens disappear when using. But if the burdens come back, this is the strategy of the enemy. He always wants you to drift farther from the light.
Try to pray in any manner that is comfortable for you. Preserve the "flower power" for His glory alone. You will stay in the light.
