Over half of this amount is generally destroyed by combustion or is lost in side-stream smoke. Around 15 to 50% of the THC in a typical marijuana joint actually gets to the bloodstream, making the actual inhaled dose closer to 3 to 12 milligrams. THC will not naturally occur in its active form in the cannabis plant. Instead, it occurs in an acidic form called tetrahydrocannabinolic acid or THC acid (THCA).
Lamps on bedside tables for example can have a scale and size that is proportionate to the height of the ceiling and the headboard or treatment on the bed wall. If your nightstand is 24â to 30â tall, Lamps should be at least 27â â 32â tall. Shorter nightstands, such as a low profile modern style that is only 18â TO 20â off the floor, call for a taller lamp to equal the visual proportion if the headboard is higher than 36â above the nightstand top.
The width of the shade should be at least as wide as the widest part of the lamp and can be up to 2x the width. 1  The shade should be 40% to 60% of the height of your lamp. For example a 30â³ lamp might have a 13â³ shade. If you buy a lamp without a shade, it typically comes with a harp, measure the harp and add an inch or so for the minimum height for your shade. Be sure to leave 2 to 3 inches of space between your bulb and the shade.
