No, eyeballs do not turn yellowish when smoking. Smoking can cause yellowing of the skin and teeth, but it does not directly affect the color of the eyeballs. However, smoking can lead to various eye problems such as dry eyes, cataracts, and age-related macular degeneration. It is important to quit smoking to protect overall eye health. **

There is no scientific evidence to suggest that smoking weed directly causes hair to turn white. Hair turns white due to a natural aging process, genetics, or other factors such as stress. While smoking weed may have other effects on the body and overall health, there is no known direct link between smoking weed and causing hair to turn white. **

Potatoes turn brown when cooking due to a chemical reaction called enzymatic browning. When the cells of the potato are damaged during cooking, an enzyme called polyphenol oxidase is released and reacts with oxygen in the air. This reaction causes the potato to turn brown. This process can be slowed down by adding an acid, such as lemon juice, to the potatoes before cooking, or by cooking them quickly at high temperatures. **

The water turns blue with homemade activated charcoal because the charcoal is able to absorb impurities and toxins from the water, leaving it clear and clean. The blue color is likely a result of the charcoal's ability to remove organic compounds and other contaminants that can cause discoloration. As the charcoal absorbs these impurities, the water becomes clearer and takes on a blue hue. **

When a person smokes marijuana, THC (the active ingredient in marijuana) causes blood vessels to dilate, leading to a drop in blood pressure. This drop in blood pressure can reduce the amount of blood flow to the skin, causing the person to appear pale or have a lighter complexion. Additionally, marijuana can also affect the autonomic nervous system, which controls bodily functions like heart rate and blood pressure, further contributing to the paleness in some individuals. **

Walls turn yellow from chain smoking due to the accumulation of nicotine and tar residue that is released into the air when smoking. These substances can stick to surfaces, including walls, and over time, they can build up and create a yellowish discoloration. The more cigarettes that are smoked in a room, the faster the walls will turn yellow. Regular cleaning and painting can help to remove or cover up the yellow stains caused by chain smoking. **

People may turn pale after smoking weed due to a drop in blood pressure caused by the active compounds in marijuana. THC, the main psychoactive component in cannabis, can dilate blood vessels and lower blood pressure, leading to a decrease in blood flow to the skin. This reduced blood flow can result in a paler complexion as less blood reaches the surface of the skin. Additionally, the relaxation effects of marijuana can also contribute to a paler appearance as the body's overall stress response is dampened. **

The outdoor lighting may not be turning on automatically anymore due to a malfunction in the light sensor or timer that controls the automatic function. It could also be caused by a power outage or a tripped circuit breaker disrupting the electrical supply to the lights. Another possibility is that the bulbs in the outdoor lighting fixtures have burned out and need to be replaced. It would be advisable to check these potential issues to determine the cause of the problem and address it accordingly. **
