Marijuana: Guys, Just Say No

Drugs are bad.

Even marijuana. The medical studies below from MEDLINE confirm, not even marijuana is innocuous and benign. One of the below studies shows that marijuana can increase the probability of lifelong psychosis: the more one smokes, the stronger marijuana one smokes, the higher the chance of lifelong schizophrenia. The other study shows that marijuana is not good for male sexual health. Period. Does any man want to be unable to perform in bed AND loco? Not me. Do yourself a favor, do not break the law, it is not cool. Live clean, eat clean, have good habits, and get your sleep. You will be happier in the long run. The other way is a fool’s highway. This article was written for the gentlemen, but the same rules for drugs and clean living apply for the ladies. What is good for the goose is good for the gander, whatever you may believe.

Cannabis, psychosis and schizophrenia: unravelling a complex interaction.

Hamilton I1.

Abstract: The relationship between cannabis and psychosis and schizophrenia has tested the field of addiction for decades, and in some ways serves as measure of our ability to provide a credible contribution to public health. As cannabis is used widely, many people are interested in the risks the drug poses to mental health. This paper focuses upon a seminal study examining this, the trajectory of subsequent research findings and what this has meant for understanding and communicating risk factor information. These studies provided evidence of a dose-response relationship between cannabis and psychosis, and that for those individuals with schizophrenia cannabis exacerbated their symptoms. The findings fit with a multi-causal model in which vulnerability interacts with a precipitating agent to produce a disease outcome. Even though this is a common model in epidemiology, it has proved difficult to communicate it in this case. This may be because at a population level the increased risk is weak and the vulnerabilities relatively rare. It may also be because people bring strongly held preconceptions to interpreting a complex multi-causal phenomenon.

Sexual dysfunction in men diagnosed as substance use disorder.

Kumsar NA1, Kumsar Ş2, Dilbaz N3.

Abstract: Illicit drugs are often used as aphrodisiacs to enhance sexual performance and/or pleasure; however, the available data suggest that most illicit drugs have adverse effects on erection, sexual desire and ejaculation latency in males and that these effects are not fully understood. This study aimed to determine the effect of illicit drug abuse on male sexual function, based on the International Index of Erectile Function (IIEF) score. This descriptive study was conducted at the Alcohol and Substance Research Treatment and Education Center, Ankara, Turkey. Males diagnosed as substance use disorder according to DSM-IV (n = 101) were included as the patient group, and age-matched healthy male volunteers (n = 43) were included as the control group. A 30-item sociodemographic interview form developed by researchers and the 15-item IIEF were administered to all the participants. Data were compared between the patient and control groups. Mean IIEF score was 46.7 ± 3.3 in the patients that used alcohol, 23.7 ± 3.3 in the opioid users, 34.1 ± 5.3 in the ecstasy users, 43.5 ± 4.2 in the cannabis users and 55.3 ± 1.6 in the control group. There was not a significant difference between the alcohol and cannabis users’ mean IIEF scores and that in the control group (P > 0.05 and >0.05 respectively), whereas there was a significant difference between the opioid and ecstasy users’ mean IIEF scores and that in the control group (P < 0.001 and <0.001 respectively). All IIEF subscale scores in the opioid users were significantly lower than in the control group (P < 0.001). IIEF erectile function, sexual desire and general satisfaction subscale scores were significantly lower in the ecstasy users than in the control group (P < 0.001, <0.005 and <0.001 respectively). In the alcohol users only, the IIEF general satisfaction subscale score was lower than in the control group (P < 0.005).
