The symptoms of Cannabis Sativa very much resemble those of Cannabis Indica. In fact, many homoeopaths use one for the other, however, they also tend to annul each other.The symptoms of Cannabis Sativa are more intense than those of Cannabis Indica. For example, the double personality in Cannabis Indica is well known. The patient feels confident that he belongs to both the worlds. On the other hand, in Cannabis Sativa, the patient has persistent doubt of his personal being. He cannot definitely place himself. He loses control over his speech and writing. While writing, he frequently changes the words. His speech is incomprehensible.  There is frequent and unnecessary mixing up of words. While talking, he feels as if somebody else is talking. Psychiatrists have extensively studied this condition but cannot cure it and just prescribe tranquilizers. In homoeopathy however, the appropriate remedy can cure the patient.A Cannabis Sativa patient feels as if drops of cold water are falling on the top or the back of his head.

The eyes of a Cannabis Sativa patient are congested with blood.

The veins become visibly prominent in and around the eyes. The nose also bleeds. One cheek is red, while the other is pale. This also occurs in Pulsatilla. In Cannabis Sativa, there is dryness of the mouth and throat. There is a feeling of choking and difficulty in swallowing.  The patient feels awfully tired.

The kidneys get inflamed. Urine comes in drops, associated with a burning sensation (scalding micturition). At the end of the micturition, there is a sensation of severe stitching type of pain. The severe spasm at the urethra and the meatus cause great discomfort. There is pain in the urethra, which the patient feels while walking as well.  Asthma too is a symptom of Cannabis Sativa, associated with rumbling over the chest. In fresh air, the patient feels relieved.

Cannabis Sativa may very well be the remedy for symptoms of the bladder associated with asthma. In fact, many chest problems are the result of suppression of gonorrhoea causing asthma and its deleterious effect on the urethra. Cannabis Sativa is very useful in treating the urethritis caused by gonorrhoea associated with symptoms of asthma. In Cannabis Sativa, the patient feels as if drops of water are pouring out of the heart. There is palpitation along with the feeling of pain.  Knees hurt while going up the stairs and the legs feel heavy. Lying down, also aggravates the symptoms.
