&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Acetyl-Fentanyl&amp;#039;&amp;#039;&amp;#039; is an opioid analgesic substance that is an analogue of Fentanyl. It&amp;#039;s potency is roughly ~6.67 times that of Morphine. Making it ~15 times less potent than its parent compound Fentanyl. &lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
Not much is currently known about the history of Acetyl-fentanyl, except that it was discovered around the same time as fentanyl, and has no currently acceptable medical use. Side effects of Acetyl-Fentanyl and other Fentanyl analogues are similar to those of Fentanyl. &lt;br /&gt;
&lt;br /&gt;
== Dosage ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|+ Oral&lt;br /&gt;
|-&lt;br /&gt;

|-&lt;br /&gt;
| Common || 4-6 mg&lt;br /&gt;
|-&lt;br /&gt;

| Light || 1-3 mg&lt;br /&gt;
|-&lt;br /&gt;
| Common || 3-5 mg&lt;br /&gt;
|-&lt;br /&gt;
| Strong || 5-7 mg+&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
NOTE: ~3.75mg Freebase = ~125ug Fentanyl IV = ~10mg Morphine IV&amp;#039;d. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Duration ==&lt;br /&gt;
