While it may be possible, the substance you are referring to is a Schedule I substance under the Controlled Substance Act of 1970 and therefore should not be handled without proper permits.
No, it will not. Crack is simply cocaine prepared with baking soda in a way that makes it smokeable so a drug test performed on someone who has taken crack and someone who has taken cocaine will return the same chemical signature.
Cocaine refers to the drug in its powder form, while crack is cocaine that has been processed into a rock crystal, typically smoked. Crack is a more potent and fast-acting form of cocaine, leading to a quicker and more intense high. Additionally, crack is generally cheaper and more addictive than powder cocaine.
Cocaine is generally snorted which does not produce any fumes. However, crack cocaine is smoked and being in a room with someone smoking crack could cause a contract "high". Cocaine Hydrochloride is very dangerous and should be avoided.
to alter the way they are perceiving experience (to get high)
YES
Crack cocaine is typically smoked. It is heated and inhaled, producing a short but intense high due to its rapid absorption into the bloodstream. The effects of crack are felt almost immediately and last for only a few minutes, leading to a cycle of repeated use to maintain the high.
it trigers release of dopeimen in the brain in large amounts that chemical is what is released when you do something good as a reward so over time you brain and body starts to think crack is a reward
Tweak can mean being high, to do crack or cocaine, and many other things.
It is possible to test "dirty" from second hand smoke from crack cocaine. Second hand smoke lingers and can be inhaled through normal breathing.
Sometime in the late 1970s, somebody figured out that if you boil cocaine with baking soda and other household chemicals, it produces a rock-like substance that burns at a lower temperature than regular cocaine. This substance is "crack." Since crack burns at a lower temperature than regular cocaine, it is easier to smoke. And, since crack is essentially nothing more than diluted cocaine, it can be sold at a cheaper price than regular cocaine. The cheap price is what caused the crack epidemic in the 1980s, as people who normally would not have been able to afford the steep price of a cocaine addiction could now get high every day for cheap. That is, essentially, the reason it was invented: cocaine is expensive. A cheaper form of cocaine garners more customers. For example, say a cocaine dealer has 50 regular customers who buy from him every day, and 200 other customers who only buy from him once a month, because they can't afford to buy cocaine every day. Now, say the dealer starts selling crack cocaine, as well as regular cocaine. Now he has 50 customers who buy cocaine from him every day, and 200 other customers who now buy crack from him every day (instead of buying regular cocaine from him once a month).
Crack cocaine was first developed in the early 1980s, with its popularity increasing throughout the decade. It is derived from powder cocaine but is processed using baking soda to create small rocks or chunks that can be smoked, leading to a faster and more intense high compared to powder cocaine.
Crack is just a smokeable, freebase form of powder cocaine (AKA blow, coke, nosecandy, snow, yayo, etc.). The effects are almost exactly the same as powder cocaine. Increased energy, excitability and attention with slight euphoria. The only differences between the two are as follows: Onset: <30 seconds (~25-30mins for powder) Length: 5-10mins (30+mins for powder) Cost: ~$20USD/gram (Up to $100USD/gram for powder) The high from crack is also stronger than the high from powder cocaine. Physiologically-wise, crack is more addictive than power cocaine and not as safe being it is possible (And is often the case with cheaper crack), the manufacturer may have not purified the finished product and there is still chemicals left from manufacturing which can damage your lungs a lot more. As far as the manufacturing of crack, it is quite simple to create crack. The majority of powder cocaine available on the street is actually a salt form of cocaine, usually hydrochloride which is what is used in making crack. The manufacturing of crack involves breaking down baking powder in powder cocaine which dissolves the hydrochloride from the cocaine, leaving the freebase form which is usually then rolled into "rocks."
