==Toxicity and harm potential==
==Toxicity and harm potential==
[[Benzodiazepines]] and thienodiazepines are essentially identical in their pharmacological action, subjective effects, toxicity and harm potential. They can therefore be treated similarly in the appropriate efforts necessary to maximize harm reduction.

===Lethal dosage===
The median lethal dosage varies wildly between specific substances within the thienzodiazepine class. It is because of this that one should always fully research the substance before administering it to themselves or others.

Similar to benzodiazepines, thienodiazepine discontinuation is notoriously difficult; it is potentially life-threatening for individuals using regularly to discontinue use without tapering their dose over a period of weeks. There is an increased risk of [[high blood pressure]], [[seizures]], and death.<ref>A fatal case of benzodiazepine withdrawal. (PubMed.gov / NCBI) | http://www.ncbi.nlm.nih.gov/pubmed/19465812</ref> Drugs which lower the seizure threshold such as [[tramadol]] should be avoided during withdrawal. Abrupt discontinuation also causes rebound stimulation which presents as [[anxiety]], [[wakefulness|insomnia]] and restlessness.

It is safest to reduce the dose each day by a very small amount, for a couple of weeks until close to abstinence. If using a short half-life thienodiazepine, a longer acting substance can be substituted. Symptoms may still be present, but their severity will be reduced significantly. For more information on tapering from thienodiazepine in a controlled manner, please see [http://www.benzo.org.uk/manual/bzcha02.htm this guide]. Small amounts of [[alcohol]] can also help to reduce the symptoms.

The duration and severity of withdrawal symptoms depends on a number of factors including the half-life of the substance used, tolerance and the duration of abuse. Major symptoms will usually start within just a few days after discontinuation and persist for around a week for shorter lasting thienodiazepines. Thienodiazepines with longer half-lives will exhibit withdrawal symptoms with a slow onset and extended duration.

*'''[[Volumetric liquid dosing]]''' - If one's thienodiazepines are in powder form, they are unlikely to weigh out accurately without the most expensive of scales due to their extreme potency. To avoid this, one can dissolve the thienodiazepine volumetrically into a solution and dose it accurately based upon the methodological instructions linked within this tutorial [[Volumetric liquid dosing|here]].
