Hello! I am concerned about your problems regarding haemorrhoids . I would like to inform you that constipation is one of the major factor for haemorrhoids .Steps to avoid constipation should be taken which includes diet containing green leafy vegetables, high fibre content . Also you took medication and are not relieved , surgical correction may be necessary. Now a days , day care surgery with minimal stay in hospital are carried out . I would consider surgery as an option if symptoms not alleviate. Diet you take following smoking marijuana is more important factor than marijuana itself .
