Regarding gender of the child, many studies have suggested dissatisfaction in infants gender (birth of a baby girl) is a risk factor for PPD. This is because in some Asian cultures, married couples are expected by the family to have at least one son to maintain the continuity of the bloodline which might lead a woman to experience PPD if she cannot give birth to a baby boy. Europe
There is a general assumption that Western cultures are homogenous and that there are no significant differences in psychiatric disorders across Europe and the USA. However, in reality factors associated with maternal depression, including work and environmental demands, access to universal maternity leave, health care, and financial security, are regulated and influenced by local policies that differ across countries. For example, European social policies differ from country-to-country contrary to the US, all countries provide some form of paid universal maternity leave and free health care. Studies also found differences in symptomatic manifestations of PPD between European and American women. Women from Europe reported higher scores of anhedonia, self-blaming, and anxiety, while women from the USA disclosed more severe insomnia, depressive feelings, and thoughts of self-harming. Additionally, there are differences in prescribing patterns and attitudes towards certain medications between the US and Europe which are indicative of how different countries approach treatment, and their different stigmas. Africa
Africa, like all other parts of the world struggles with a burden of postpartum depression.
Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method). Investigators have suggested that this is an important factor in marijuanas effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.Researchers confirmed that THC exerts its most prominent effects via its actions on two types of cannabinoid receptors, the CB1 receptor and the CB2 receptor, both of which are G protein-coupled receptors. The CB1 receptor is found primarily in the brain as well as in some peripheral tissues, and the CB2 receptor is found primarily in peripheral tissues, but is also expressed in neuroglial cells. THC appears to alter mood and cognition through its agonist actions on the CB1 receptors, which inhibit a secondary messenger system (adenylate cyclase) in a dose-dependent manner. Via CB1 receptor activation, THC indirectly increases dopamine release and produces psychotropic effects. CBD also acts as an allosteric modulator of the μ- and δ-opioid receptors. THC also potentiates the effects of the glycine receptors. It is unknown if or how these actions contribute to the effects of cannabis. Chemistry
Chemical composition
The main psychoactive component of cannabis is THC, which is formed via decarboxylation of THCA from the application of heat. Raw leaf is not psychoactive because the cannabinoids are in the form of carboxylic acids.
