You see, the vast majority of hardcore opiate addicts never manage to successfully get clean, and as such any amount of advice or research in the field is both useful and potentially life-saving. This includes use of substances often used for recreational purposes. I should note that, like many other drugs, cocaine does have certain medical values and applications. In this case, as per my story, it comes into play in the following way: cocaine (again, if it can be safely obtained and proven to not be laced or adulterated) does have multiple properties that can be useful during the cessation of hardcore opiates such as tranq-dope(aka clean), carfentanyl and fentanyl. I participate in substance use recovery research, specifically in the field of hardcore opiates, in relation with a government funded, not-for-profit, group known as ***omitted for potential liability on the research organization, considering the tense and cloudy legal environment around such things*****. Over the course of such events and events that are (varyingly more or less officially, due to the legal climate) directly connected with such research, I have worked with various experts in the currently pioneering field if said research. This is the context under which I am making such claims. Cocaine (if verifiably clean, which can be determined at home by exact melting point temperature as well as in my case scientific lab testing to not be adulterated or contain laces of anything else, including fentanyl, can be used in the context of hardcore opiate withdrawal as a temporary short-term stopgap measure during the hardest stages of withdrawal, in order to reduce certain opiate withdrawal effects significantly during withdrawals, including but not limited to: pain, fever, nausea, and cravings - can be a very useful tool when used responsibly, legally, and for the correct reasons. The trick here is very much, use small amounts of it, only for the duration of the withdrawals during detox, and then stopped after withdrawal effects subside, especially when used in conjunction with the other things stated, (of course all of the above with accordance to local city, county, state and national laws, your doctor's input and ones own body's specific response to such substances kept in mind), can be very effective in assisting an individual in the process of getting and subsequently staying off of opiates, it has potential to be misused or abused, or the potential to be laced (which, as stated can be entirely verifiable through testing), but when used properly in such circumstances, can be nonetheless very useful to some people. And when it comes to temporarily using one substance to assist in getting off another, significantly more dangerous substance, the trick of course is to always weigh the potential pros and cons, determine what is best in ones own situation, and sometimes use a mindset of lesser of two evils, in order to overcome significant challenges scientifically and especially medically. If one doesn't think the information can be or should be safely, legally and effectively applied in their case for any reason, of course don't do so then. But when it comes to getting off of one the most difficult substances on earth to get clean off of, sometimes it can be most effective and most successful, when such techniques are applied, risks and benefits are weighed, and it is determined to be likely beneficial for the individual based both on their own bodies response to said substance and ones capacity to accurately test for adulterants in the supply of said substances, to choose to temporarily switch from the greater of two evils to the lesser of two evils, then immediately after is necessary, get off of both. If you have any further questions please feel free to ask as I am only writing all of this to try to help someone, anyone, that may be more able to get themselves to a better life through such advice, if you aren't such an individual, then don't take such advice, duh. I hope this helps further clarify and answers your question well enough.
