Try parenting the effect into your weapon.

PHP Code:

new active_weapon = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon");
    
if (IsValidEntity(active_weapon))
{
    new particle = CreateEntityByName("info_particle_system");
        
    if (particle != -1) 
    {
        decl Float:position[3];
        GetEntPropVector(active_weapon, Prop_Send, "m_vecOrigin", position); //return Float:{0.0, 0.0, 0.0}
        DispatchKeyValueVector(particle, "origin", position);
        DispatchKeyValue(particle, "effect_name", "smoke_trail");
        DispatchKeyValue(particle, "start_active", "1");
        
        if (DispatchSpawn(particle)) 
        {
            ActivateEntity(particle);
            SetVariantString("!activator");
            AcceptEntityInput(particle, "SetParent", active_weapon);
            SetVariantString("0"); 
            AcceptEntityInput(particle, "SetParentAttachment", particle);
        }
    }
} 


I tried...

I think they meant that you don't need to set the origin manually, it'll be updated automatically after SetParantAttachement, from wiki:

PHP Code:

SetParentAttachment
 Note:    Entities must be parented before being sent this input. Use at least a 0.01 second delay between SetParent and SetParentAttachment inputs.
You can also fire a SetParentAttachment input at the child-entity to attach it to a specific attachment point on its parent. The parameter is the name of the attachment point.

The Child instantly teleports to the attachment point. This is the only method which does not maintain the offset. 


You may try this, found it after few secs of search:

PHP Code:

new active_weapon = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon");
    
if (IsValidEntity(active_weapon))
{
    new particle = CreateEntityByName("info_particle_system");
        
    if (particle != -1) 
    {
        DispatchKeyValue(particle, "effect_name", "smoke_trail");
        DispatchKeyValue(particle, "start_active", "1");
        
        if (DispatchSpawn(particle)) 
        {
            ActivateEntity(particle);            
            SetVariantString("!activator");
            AcceptEntityInput(particle, "SetParent", active_weapon, particle);            
            SetVariantString("muzzle"); 
            AcceptEntityInput(particle, "SetParentAttachment", active_weapon, particle);
        }
    }
}

so too does not work

Hmm. Has the partical been precached.

If you spawn it at your location without parenting it, can you see it?

Yes.

why not just get the player pos and adjust the x to coincide with the weapon's x

It would never look right unless u account for the player/weapon moving...the particle would remain in the same spot in the world without being parented. Constant teleporting of the particle would need to be done without parenting it to give the illusion of it being parented to the weapon. In my opinion doing it from the client would be less accurate and not look right...u swing your arms yet the particle remains in the same spot. Get the weapons vector.
